ion-toggle
Toggles are switches that change the state of a single option. They can be switched on or off by pressing or swiping them. Toggles can also be checked programmatically by setting the checked
property.
Basic Usage
On / Off Labels
Toggles can enable on/off labels by setting the enableOnOffLabels
property. This is important for accessibility as it makes it easier to differentiate between a checked and unchecked toggle.
Theming
Colors
CSS Custom Properties
CSS custom properties can be combined with standard CSS to target different parts of a toggle. We can modify the width
and height
of the toggle directly to change the size of the track, while using the --handle-width
and --handle-height
custom properties to customize the handle size.
CSS Shadow Parts
We can further customize toggle by targeting specific shadow parts that are exposed. Any CSS property on these parts can be styled and they can also be combined with CSS custom properties.
Interfaces
ToggleChangeEventDetail
interface ToggleChangeEventDetail<T = any> {
value: T;
checked: boolean;
}
ToggleCustomEvent
While not required, this interface can be used in place of the CustomEvent
interface for stronger typing with Ionic events emitted from this component.
interface ToggleCustomEvent<T = any> extends CustomEvent {
detail: ToggleChangeEventDetail<T>;
target: HTMLIonToggleElement;
}
