Tabs

A vertical list of collapsible sections: clicking a header expands its content and clicking again collapses it, either exclusively (one open at a time) or independently. Packs grouped content into limited space for on-demand expansion.

A hierarchical path like "Home / Library / Page" that states where the user sits in the information architecture: every ancestor is a link back, and the last item marks the current page. The cheapest way to keep users oriented — the name comes from the breadcrumbs Hansel dropped to find his way home. Usually placed above the page title.

A page-numbered control that slices long result sets into discrete pages: users explicitly click a page number or prev / next to fetch that slice, so the current position is always known, shareable and reversible. The controlled counterpart to infinite scrolling's endless drift — the default for search results and admin tables.

A menu of actions popping near its trigger to tuck away secondary operations and keep the interface tidy — the classic form being a "···" more button. The panel floats over content with a shadow; picking an item executes and closes, and destructive actions sit isolated below a divider in red.

A vertical navigation area pinned to one side of the page (usually the left), carrying the primary hierarchy of a product. The de facto standard of admin systems: brand and global search on top, module tree in the sidebar, content focused on the task.
