Bottom Sheet

Best Practices
When using a bottom sheet, clarity and cohesion are paramount. Bottom sheets should feel seamlessly integrated, offering just enough functionality to support the primary view. Avoid crowding the interface with excessive options or prolonged text. Smooth transitions—especially when expanding or collapsing—help users track changes visually. It’s also essential to respect screen real estate; on mobile devices, bottom sheets can easily occupy key screen areas if not carefully sized.
Style
Bottom sheets typically adopt a subtle elevation or shadow, distinguishing them from the underlying content. Rounded corners at the top edge are common, signaling that the element can be dragged or expanded. For color and typography, maintain consistency with the app’s overall theme while ensuring sufficient contrast for text and interactive elements. If the sheet is designed to dim the background content, use a translucent overlay to emphasize its temporary and contextual nature.
Content
At their core, bottom sheets should deliver task-specific information or actions. Keeping content short and organized supports quick scanning and selection, whether the sheet contains a few filters, form fields, or a concise menu. Clear labels or headings help users interpret available options at a glance. If advanced or nested actions exist, consider using collapsible sections or transitions that progressively reveal content while preserving simplicity at first sight.
Role
Supplementary Options. Provide extra controls—like filtering or sharing—that complement a primary screen without diverting users to a different page.
Additional Context. Present further details about a selected item (e.g., product specs, location data) while retaining the main interface in the background.
Short Interaction Flows. Support brief tasks—such as updating preferences or confirming a single setting—so people can quickly dismiss the sheet and return to their primary activity.
By applying bottom sheets thoughtfully, designers can deliver relevant, context-aware functionality in a compact space. This approach preserves focus on the main content while offering on-demand access to supplemental tasks.
