A mobile-oriented surface attached to the bottom edge that can open to stable heights and may support dragging.
Sidebar
A persistent region beside primary content that participates in page layout and usually contains navigation or supporting tools.
Select
A form control for choosing one or more values from predefined options without arbitrary text entry; a single-select commonly appears as a closed picker, while a multiple select may expose a list.
