API reference
Inputs
| Name | Type | Default | Binding | Description |
|---|---|---|---|---|
| label | string | Required | Input | Human-readable name for the control, action or group. |
| min | number | 0 | Input | Lowest accepted user value. The default is zero, so negative values are rejected unless you explicitly configure a negative minimum. |
| max | number | 100 | Input | Upper bound of the range or item limit, according to this control. |
| step | number | 1 | Input | Positive increment used by the increase/decrease buttons and numeric editing. Defaults to 1; configure a positive decimal such as 0.5 when needed. |
| 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. |
| decreaseLabel | string | 'Decrease' | Input | Text or accessible name used for decrease. It does not perform the action by itself. |
| increaseLabel | string | 'Increase' | Input | Text or accessible name used for increase. It does not perform the action by itself. |
Models
| Name | Type | Default | Binding | Description |
|---|---|---|---|---|
| value | number | 0 | Model · two-way | Numeric value; edits and step actions apply min, max and step. While typing, the field keeps temporary blanks, signs and decimal separators without restoring the previous digit. Blur or a step action normalizes the displayed text; an external value replacement discards the draft. |
Outputs
| Name | Payload | When it emits |
|---|---|---|
| valueChange | number | 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.
import { signal } from '@angular/core';
// Fields inside your component class
readonly value = signal<number>(0);
