Overview
Open Sheet actions open a page as a native sheet/modal on top of the user’s current page. You can customize how the sheet looks: its detents (heights), corner radius, and grabber visibility. You can also customize how the sheet behaves: if the content is scrollable, if the user can interact with the original page under the modal, and if the user can dismiss the modal by swiping down.Action Properties
