An iOS-style action sheet that slides up from the bottom of the screen. Features a title, a scrollable list of contextual actions, and a separate Cancel button that is always visible.

How it works

Trigger button opens the sheet by adding .open to both the backdrop and the sheet
The sheet uses translateY(100%) → translateY(0) for the slide-up animation
The Cancel button is rendered as a separate card below the actions, matching native iOS style
Tapping the backdrop or Cancel closes the sheet

Variants in the demo

Share — share, copy link, save image, embed
Delete — destructive confirmation pattern with a red action

When to use it

Contextual actions on a selected item
Share sheets and save dialogs
Confirmation for destructive actions (delete, leave, cancel subscription)
