API reference

Inputs

Name	Type	Default	Binding	Description
options	readonly NeuOption[]	[]	Input	Available choices. Selected values refer to option IDs, not their displayed labels.
emptyLabel	string	'No matches'	Input	Text or accessible name used for empty state. It does not perform the action by itself.
minLength	number	1	Input	Minimum text length used by this control; server validation still belongs to your application.
label	string	Required	Input	Human-readable name for the control, action or group.
disabled	boolean	false	Input	Disables user interaction. Values can still be supplied by the application.
readonly	boolean	false	Input	Prevents user editing or selection while retaining the current value.
invalid	boolean	false	Input	Marks the control invalid. Your form or application supplies the validation rule.
touched	boolean	false	Input	Field interaction state, supplied manually or through Signal Forms.
hint	string	''	Input	Field guidance shown when no error message is being displayed.
required	boolean	false	Input	Required-field presentation. Define the actual validation rule in your application form.
requiredLabel	string	'Required'	Input	Localized requirement announced with the field hint when required is true. Defaults to Required; it does not validate the value.
error	string	''	Input	Application-provided error message; combine it with the control’s invalid state.

Models

Name	Type	Default	Binding	Description
value	string	''	Model · two-way	Current edited value or selected ID(s), using the declared type. Bind a writable signal with [(value)].

Outputs

Name	Payload	When it emits
valueChange	string	Emits the updated value value. [(value)] binds this output together with its model input.
touch	void	Reports user interaction to the surrounding form or application.

Model state

Bind the signal with [(modelName)] without calling it. Use modelName() to read its value.

model-fields.ts

import { signal } from '@angular/core';

// Fields inside your component class
readonly value = signal<string>('');
