It acts as a central hub for accessing sections, features, and functionality. Use `bq-side-menu-item` inside `bq-side-menu`; side menu items rely on the parent menu to manage collapsed and selected states. ## When to use Use side menus when * A website or application has extensive content or multiple hierarchical levels * A compact and organized navigation system is necessary * Users need persistent access to primary sections while they work Do not use side menus when * The menu reduces the visibility of primary content * The interface is focused on reading or content consumption * The layout is too narrow to support persistent navigation ## Patterns Navigation items remain visible while users scroll. This gives people a persistent representation of the product structure. The collapsible view reduces the menu to a compact rail. Use it when space is constrained or when users need more room for content. For grid sizes M to XS, applicable to viewports of 768 pixels and below, display the side menu in collapsed mode. ## Anatomy BEEQ Side Menu component anatomy BEEQ Side Menu component anatomy A side menu is composed of a container, selected item state, navigation items, and optional logo and footer areas. | Part | Element | Description | | ----- | --------------------- | ------------------------------------------------------------------------ | | **1** | Container | The root `
