Bit.BlazorUI.AISchemaForm
BitAiForm renders a form the model proposed, for the user to check and submit. Rather than calling a tool with arguments it guessed, a model describes a form - as fields, or as the same JSON Schema it already uses for tool arguments - the user corrects it, and the corrected values are what execute. Every field is a core input (BitTextField, BitNumberField, BitCheckbox, BitDropdown, BitDatePicker, BitTimePicker), nested objects become groups and arrays lists the user adds to, and validation happens here rather than in the model. Fields appear as the schema streams in, and what the user typed is kept.
Notes
To use this component, you need to install the
Bit.BlazorUI.AI(opens in a new tab)
nuget package, as described in the Optional steps of the
Getting started page.
BitAiForm needs nothing but its Definition: no session and no transport. A form a model proposes usually
arrives as a structured output part whose JSON Schema an app turns into a definition with
BitAiFormDefinition.FromJsonSchema, in a renderer registered for that schema - see
BitAiStructuredDataView and the
Forms scenario. Its default button texts (Submit, Cancel), the
Submitted confirmation, the texts of its lists and the validation messages come from the strings in force
(BitAiStrings, listed in the tables below), which a
BitAiOptionsProvider or ConfigureUi localizes.
Security: validation runs here because a model asked to check its own output will sometimes say yes when the
answer is no - and the values a user submits are still input: validate them again wherever they execute. A
pattern a model wrote is matched under a timeout, so a catastrophic one fails the field instead of freezing
the page; one that is not a valid regular expression is ignored.
Accessibility: each field is a core input with its own label, description and error message, which its
control points at through aria-describedby while it says aria-invalid. A nested object and a list are a
fieldset with a legend; an entry of a list of objects is a group named after the list and its place
(Speakers 2), an entry of a list of values an input named the same way, and its remove button says which entry it
removes. Once an entry is removed the focus moves to the remove button now in its place (or that of the new last
entry), or to the add button of a list left empty, rather than falling back to the top of the page. The errors the form renders itself (a list's, a
checkbox's) are announced as alerts.
Usage
Every example is live. Open its code to see exactly what produced the component running underneath.
Basic
A BitAiFormDefinition is a title, a description and its Fields, each a BitAiFormField named
after the key its value is submitted under (and labelled after it, unless it has a Label). OnSubmit
is handed the values of a valid form, as text keyed by field name.

Field types
Type picks the control, a BitAiFieldType: a text box, a multi-line one, a number, a checkbox, a
dropdown over Options (labelled by OptionLabels), a date, a date and time, a time, an email, a URL
or a password. Value prefills it, Placeholder and Description help with it. Whatever the
control, the value is submitted as invariant text: 2, true, 2026-10-23, 14:30.

JSON Schema
BitAiFormDefinition.FromJsonSchema builds a form from a JSON Schema object, the vocabulary a model already
uses for tool arguments: type, format, enum with enumNames, default,
title, description, required and the rest. A second argument prefills it, ahead of the
defaults. OnSubmitJson hands the values back as JSON of the shape of the schema, numbers and booleans
typed as such.

Schema keywords
The rest of the vocabulary FromJsonSchema reads, one property each in the form below:
a const is a read-only field holding its value (Event), and so is a readOnly property with a
default (Seat); a oneOf - or anyOf - of const values is a dropdown labelled by
their titles (Ticket); format date-time is a date and time picker and password a masked
input; a type that also allows "null" (["string", "null"], an anyOf with a null
alternative, or OpenAPI's nullable: true) makes a field optional even when it is required
(Phone), and examples become its placeholder; a local $ref into $defs (or
definitions) is followed, with a title or description written beside it winning over the
target's (Contact). x-enumNames labels an enum like enumNames, and the draft-4
boolean exclusiveMinimum / exclusiveMaximum are read too. A keyword of the wrong kind is ignored and an
unknown shape falls back to a text box, since a model wrote the schema.

Validation
Submit checks every field: required, minLength / maxLength, pattern,
minimum / maximum and their exclusive forms, whole numbers (integer), multipleOf, the
format of an email, a web address (an absolute http or https URL) or a date, and a choice the options do not offer.
Each error is shown on its field - whose input points at it through aria-describedby and says
aria-invalid - and clears as the field is edited; OnSubmit is raised only once the form is valid.
The messages are the validation strings of the AI options (see the table below). Press Sign up with the
form empty, then fix it: try a username with capitals, an age of 17, a website without its https://, and a donation
of 7 or of 1000.
Create an account
3 to 16 lowercase letters, digits or underscores.
Optional, in steps of 5, under 1000.
Nested objects & lists
An object with properties becomes a group of fields (BitAiFieldType.Object) and an
array a list the user adds entries to and removes them from (BitAiFieldType.Array): a list of
inputs for scalar items, repeatable groups for object ones, held between minItems and
maxItems. The values are kept flat by path (venue.city, tags[0], speakers[1].name),
and OnSubmitJson puts the shape back together.

Streaming schema
A model streams its schema as partial JSON. Rebuilt from the part on every delta, the definition grows field by
field, and the form seeds each field once: a field that streams in later never overwrites what the user already
typed. The scripted transport here proposes a booking form - start typing in it while it is still arriving. Busy
holds the submit back until the whole schema is in, so a field that has not arrived yet cannot be skipped.
Actions & state
SubmitLabel and CancelLabel of the definition name the buttons. Cancel is shown on a form with an
OnCancel, which it raises (an empty CancelLabel hides it all the same); the other forms of this
page have none, and so no Cancel. Busy turns the actions off while the submission is in
flight; Submitted replaces them with a confirmation once it is done. Values reads what the user has
typed so far, without submitting. A Disabled form turns every input and action off.

Cascading parameters
BitParams with a BitAiFormParams sets the Classes and Styles of the parts - and the
parameters every component shares, such as Disabled or Dir - of every form inside it, rather than
the definition and the callbacks of a single form. A form keeps what it sets itself: the second one gives
Styles of its own, so the cascaded ones do not reach it.

Style & Class
Style and Class reach the root, Styles and Classes each part (the buttons take the
class-styles of BitButton). The inputs are core components, restyled through their own variables. The public
--bit-AiForm-* variables (see the CSS variables table) inherit, so set on :root, a container or a
form's Style they re-skin every form below.

CSS variables
The public custom properties this component reads off its root, for what no parameter covers.
Every variable is read with a fallback and never declared by the component, so it inherits like any other custom property:
set one on :root (or in a [bit-theme] block) to restyle every instance, on any ancestor to restyle the ones inside it,
or on the Style of one instance to restyle it - and any instance nested inside it, which inherits the value too; a parameter changes one alone,
as does the real CSS property on the instance's Style / Styles when that property does not inherit (opacity: 1 keeps
one disabled instance undimmed without undimming a disabled one inside it), while an inherited one such as color or
font-family also reaches the nested instances that do not set it themselves. Leave a variable unset and the component
falls back to the theme token beside it.

API
Every parameter, public member, sub-class and enum this component exposes.
BitAiForm parameters
| Name | Type | Default value | Description |
|---|---|---|---|
| Busy | bool | false | Turns the actions off while something else is in flight - the submission being saved, a reply being generated - while the inputs stay editable. A press that still reaches a button submits or cancels nothing. |
| Classes | BitAiFormClassStyles? | null | Custom CSS classes for different parts of the form. |
| Definition | BitAiFormDefinition | null | The form to render (required): its title, description, fields and button labels. Each field is seeded once with its Value; a definition handed in again - rebuilt as a schema streams in - keeps what the user typed in every field whose control did not change (a bound, a choice or a nested field streaming in changes nothing typed, and a prefill streaming in fills a scalar field only while it still holds the previous prefill, so what the user typed wins; an object or a list is seeded again with a new prefill), seeds the new ones, and drops the values of fields that are gone. |
| OnCancel | EventCallback | The callback raised when the user presses Cancel. The button is shown only while it is set, and unless the CancelLabel of the definition is an empty string. | |
| OnSubmit | EventCallback<IReadOnlyDictionary<string, string?>> | The callback raised with the collected values when the user submits a valid form: a copy of the flat values, as invariant text keyed by field path (name, venue.city, tags[0], speakers[1].name). A form with errors shows them on its fields and raises nothing. See OnSubmitJson for the typed, nested shape. | |
| OnSubmitJson | EventCallback<JsonElement> | The callback raised with the values as JSON in the shape of the schema the form came from (BitAiFormDefinition.ToJson): nested objects and arrays rebuilt from the paths, numbers and booleans encoded as such. Raised after OnSubmit. | |
| Styles | BitAiFormClassStyles? | null | Custom CSS styles for different parts of the form. |
| Submitted | bool | false | Whether the form has already been submitted, which replaces the actions with a confirmation and stops any further submission - set it once the submission has been handled, so the turn reads as done. |
BitAiForm public members
| Name | Type | Default value | Description |
|---|---|---|---|
| Values | IReadOnlyDictionary<string, string?> | The values as they currently stand, keyed by field path, valid or not - what the user has typed so far, read without submitting (through a @ref). |
BitComponentBase parameters
| Name | Type | Default value | Description |
|---|---|---|---|

BitAiFormDefinition properties
A form the model asked for, which the user fills in and submits back: a record of its fields and labels, built in code or from a JSON Schema.
| Name | Type | Default value | Description |
|---|---|---|---|
| Fields | IReadOnlyList<BitAiFormField> | [] | The fields, in display order. |
| Title | string? | null | A heading above the form. |
| Description | string? | null | A line of explanation under the heading. |
| SubmitLabel | string? | null | The text of the submit button; the Submit text of the AI options' string table while it is null, so a form a model proposes is labelled in the language of the app. |
| CancelLabel | string? | null | The text of the cancel button; the Cancel text of the string table while it is null, and no cancel button at all when it is an empty string. The button is shown only on a form with an OnCancel. |
| FromJsonSchema(schema, values?) | BitAiFormDefinition (static) | Builds a form from a JSON Schema object (its title and description become the form's): type - including ["string", "null"], an anyOf with a null alternative or nullable: true, which make a field optional -, format (date, date-time, time, email / idn-email, uri / url / uri-reference / iri, password, textarea), enum with enumNames or x-enumNames, oneOf / anyOf of const values (labelled by their titles), const and readOnly (read-only fields), default, title, description, required, minimum / maximum, exclusiveMinimum / exclusiveMaximum (as numbers, or draft 4's flags), multipleOf, integer, minLength / maxLength, pattern, examples (a placeholder), nested object properties, array items with minItems / maxItems, and local $refs into $defs or definitions (a title or description beside the $ref wins). Objects and arrays nested deeper than 8 levels are edited as JSON text. The optional values, keyed by property name, prefill it ahead of the defaults. Never throws on a malformed schema: a keyword of the wrong kind is ignored and an unknown shape falls back to a text box. | |
| ToJson(values) | JsonElement | Builds JSON in the shape of the form from the flat values a BitAiForm collects - nested objects and arrays rebuilt from the paths, numbers and booleans encoded as such (by each field's JsonType) - with one member per field that has a value, and a required field written even when it is empty (as null, or an empty object or array). What OnSubmitJson is handed. | |
| Path(parent, name) | string (static) | The path of a member: its name at the root (parent null), else parent.name - venue.city. The keys of the flat values of OnSubmit and Values. | |
| IndexPath(arrayPath, index) | string (static) | The path of one entry of a list, by its zero-based index: tags[0], speakers[1] (and speakers[1].name for a member of it). | |
| CountItems(values, arrayPath) | int (static) | How many entries a list holds in the flat values: the highest index found under its path, plus one. For an app reading a list out of the values of OnSubmit or Values. |
BitAiFormField properties
One field of a form: a record created as new BitAiFormField(name, label?) with its other members set by initializer.
| Name | Type | Default value | Description |
|---|---|---|---|
| Name | string | The key the value is submitted under. | |
| Label | string? | null | The visible label. Falls back to the name written as a label (DisplayLabel): firstName reads First Name. |
| Type | BitAiFieldType | BitAiFieldType.Text | The control the field renders as. |
| Description | string? | null | Help text under the control (under the legend of a group). |
| Placeholder | string? | null | Placeholder text inside the control. |
| Value | string? | null | The initial value, which a model may prefill, as invariant text. For an Array field, the JSON text of the initial array. A Boolean field without one starts, and is submitted, as false - the unchecked box it shows. |
| Required | bool | false | Whether the field must be filled in (an Array field: hold at least one entry). A checkbox is never required to be checked. |
| ReadOnly | bool | false | Whether the field is shown but cannot be edited, as for a schema const or readOnly. A read-only list can be neither added to nor removed from. |
| Options | IReadOnlyList<string>? | null | The choices of a Select field, as the values that are submitted. A value outside them fails validation. |
| OptionLabels | IReadOnlyList<string>? | null | Display labels for Options, in the same order, when they differ from the values. |
| Minimum | double? | null | The smallest value a number accepts ("must be at least"); also the lowest value of its spin buttons. |
| Maximum | double? | null | The largest value a number accepts ("must be at most"); also the highest value of its spin buttons. |
| ExclusiveMinimum | double? | null | A value a number must be strictly greater than ("must be greater than"); the lowest value of its spin buttons when there is no Minimum. |
| ExclusiveMaximum | double? | null | A value a number must be strictly less than ("must be less than"); the highest value of its spin buttons when there is no Maximum. |
| MultipleOf | double? | null | A step a number must be a multiple of, which is also the step of its spin buttons. |
| Integer | bool | false | Whether a number accepts whole numbers only (a schema integer); its spin buttons step by 1. |
| MinLength | int? | null | The fewest characters a text, email, URL or password value may have ("must be at least N characters"). |
| MaxLength | int? | null | The most characters a text, email, URL or password value may have; the input stops taking more. |
| MinItems | int? | null | The fewest entries an Array field may hold ("needs at least N items"). |
| MaxItems | int? | null | The most entries an Array field may hold; its add button turns off at the most. |
| Pattern | string? | null | A regular expression the value must match, run under a timeout: one that takes too long fails the field. |
| Fields | IReadOnlyList<BitAiFormField>? | null | The nested fields of an Object field. |
| Items | BitAiFormField? | null | The template of each entry of an Array field: a scalar field for a list of inputs, an Object field for repeatable groups. |
| JsonType | string? | null | The JSON Schema primitive the value is submitted as by ToJson - string, integer, number, boolean, object or array; null means string. |
| DisplayLabel | string | The label shown for the field: Label, else the name written as a label. |
BitAiStrings (form) properties
The texts of the form, members of the BitAiStrings of the options in force. Every member is virtual: a subclass overrides the ones it words differently and is handed as the Strings of the BitAiUiOptions - of a BitAiOptionsProvider, or of ConfigureUi (see /components/ai/optionsprovider#strings). The label in a message is the field's DisplayLabel - for an entry of a list of values, the list's label and the entry's place (Tags 2).

| FieldNotADate(label) | string | "{label} must be a valid date or time." | A Date, DateTime or Time field holding something that does not parse as one (a prefill a model got wrong). |
| FieldTooFewItems(label, minimum) | string | "{label} needs at least {minimum} item(s)." | A list with fewer entries than MinItems. |
| FieldTooManyItems(label, maximum) | string | "{label} can have at most {maximum} item(s)." | A list with more entries than MaxItems - one prefilled past it, since the add button stops there. |
