Bottom sheets are a common feature in mobile interfaces that offer a flexible way to present additional content without navigating away from the main screen.
They help reduce cognitive load and improve loading and rendering performance, especially on handheld devices with limited screen space.
Bottom sheets slide up from the bottom of the screen, providing more space than traditional dialogs by snapping to three out of four edges.
Modal bottom sheets render the main document inert while non-modal ones pair with the main document.
Designing bottom sheet UX involves using all horizontal space, visual cues for interactivity, and subtle transitions.
Prevent accidental dismissal by placing a close button near the top-left corner and avoiding large clickable areas that can dismiss the bottom sheet.
Introduce subtle transitions such as sliding up from below and keep content low-density for better user experience.
Consider navigation possibilities as bottom sheets are not traditionally included in navigation history.
Bottom sheets offer a page-in-page experience with reduced cognitive load, making tasks quicker while maintaining the user's place in the main document.
Overall, simplify bottom sheets by using horizontal space effectively, limiting interactivity, and employing simple transitions.
