/**
|
|
* @summary Drawers slide in from a container to expose additional options and information.
|
|
* @documentation https://shoelace.style/components/drawer
|
|
* @status stable
|
|
* @since 2.0
|
|
*
|
|
* @dependency sl-icon-button
|
|
*
|
|
* @slot - The drawer's main content.
|
|
* @slot label - The drawer's label. Alternatively, you can use the `label` attribute.
|
|
* @slot header-actions - Optional actions to add to the header. Works best with `<sl-icon-button>`.
|
|
* @slot footer - The drawer's footer, usually one or more buttons representing various options.
|
|
*
|
|
* @event sl-show - Emitted when the drawer opens.
|
|
* @event sl-after-show - Emitted after the drawer opens and all animations are complete.
|
|
* @event sl-hide - Emitted when the drawer closes.
|
|
* @event sl-after-hide - Emitted after the drawer closes and all animations are complete.
|
|
* @event sl-initial-focus - Emitted when the drawer opens and is ready to receive focus. Calling
|
|
* `event.preventDefault()` will prevent focusing and allow you to set it on a different element, such as an input.
|
|
* @event {{ source: 'close-button' | 'keyboard' | 'overlay' }} sl-request-close - Emitted when the user attempts to
|
|
* close the drawer by clicking the close button, clicking the overlay, or pressing escape. Calling
|
|
* `event.preventDefault()` will keep the drawer open. Avoid using this unless closing the drawer will result in
|
|
* destructive behavior such as data loss.
|
|
*
|
|
* @csspart base - The component's base wrapper.
|
|
* @csspart overlay - The overlay that covers the screen behind the drawer.
|
|
* @csspart panel - The drawer's panel (where the drawer and its content are rendered).
|
|
* @csspart header - The drawer's header. This element wraps the title and header actions.
|
|
* @csspart header-actions - Optional actions to add to the header. Works best with `<sl-icon-button>`.
|
|
* @csspart title - The drawer's title.
|
|
* @csspart close-button - The close button, an `<sl-icon-button>`.
|
|
* @csspart close-button__base - The close button's exported `base` part.
|
|
* @csspart body - The drawer's body.
|
|
* @csspart footer - The drawer's footer.
|
|
*
|
|
* @cssproperty --size - The preferred size of the drawer. This will be applied to the drawer's width or height
|
|
* depending on its `placement`. Note that the drawer will shrink to accommodate smaller screens.
|
|
* @cssproperty --header-spacing - The amount of padding to use for the header.
|
|
* @cssproperty --body-spacing - The amount of padding to use for the body.
|
|
* @cssproperty --footer-spacing - The amount of padding to use for the footer.
|
|
*
|
|
* @animation drawer.showTop - The animation to use when showing a drawer with `top` placement.
|
|
* @animation drawer.showEnd - The animation to use when showing a drawer with `end` placement.
|
|
* @animation drawer.showBottom - The animation to use when showing a drawer with `bottom` placement.
|
|
* @animation drawer.showStart - The animation to use when showing a drawer with `start` placement.
|
|
* @animation drawer.hideTop - The animation to use when hiding a drawer with `top` placement.
|
|
* @animation drawer.hideEnd - The animation to use when hiding a drawer with `end` placement.
|
|
* @animation drawer.hideBottom - The animation to use when hiding a drawer with `bottom` placement.
|
|
* @animation drawer.hideStart - The animation to use when hiding a drawer with `start` placement.
|
|
* @animation drawer.denyClose - The animation to use when a request to close the drawer is denied.
|
|
* @animation drawer.overlay.show - The animation to use when showing the drawer's overlay.
|
|
* @animation drawer.overlay.hide - The animation to use when hiding the drawer's overlay.
|
|
*
|
|
* @property modal - Exposes the internal modal utility that controls focus trapping. To temporarily disable focus
|
|
* trapping and allow third-party modals spawned from an active Shoelace modal, call `modal.activateExternal()` when
|
|
* the third-party modal opens. Upon closing, call `modal.deactivateExternal()` to restore Shoelace's focus trapping.
