Buttons

Prop	Default	Type	Description
`_alertDialogCancel`	`{ btn: 'solid-gray', label: 'Cancel'`	`AlertDialogCancelProps`	The cancel button props.
`_alertDialogAction`	`{ btn: 'soft-primary', label: 'Continue' }`	`AlertDialogActionProps`	The action button props.

The AlertDialogActionProps and AlertDialogCancelProps extends the NButton and NLink components, which means that you can use all the props from the Button and Link components.

Slots

Name	Props	Description
`default`	-	Allows advanced customization using sub-components, replacing the default structure.
`content`	-	Replaces the entire default content container within the dialog popup.
`trigger`	`open`	The trigger button used to open the dialog.
`cancel`	-	Custom content for the cancel button that aborts the proposed action.
`action`	-	Custom content for the action button that confirms the destructive action.
`cancel-wrapper`	-	Override the entire default cancel button.
`action-wrapper`	-	Override the entire default action button.
`header`	-	Custom content for the header section containing title and description.
`footer`	-	Custom content for the footer section containing action and cancel buttons.
`title`	-	Custom content for the dialog title, replacing the default title prop.
`description`	-	Custom content for the dialog description, replacing the default description prop.

Use the default slot for full control over the alert dialog's structure. This allows you to compose the alert dialog using its individual sub-components (like AlertDialogAction, AlertDialogCancel, etc., listed in the Components section), similar to libraries like shadcn/ui.
