Collisions

Updated on Sep 1, 2026

The Popover lets you control collision behavior when it is not fully visible. The collision property supports the following options:

• fit moves the Popover horizontally until it is fully displayed in the viewport.
• flip flips the Popover position based on its origin and position properties.
• none renders the Popover at its original position. Use this option when the Popover receives focus on open and the page scrolls to it.
