Design a flexible sidebar for categories, filters, and deep navigation

Utilize a vertical list structure with nested items to represent subcategories and filters effectively.

Include clear section headers such as 'Regions', 'Categories', and 'Filters' to organize the content logically.

States & Interactions

Highlight the active item visually using a background color and a left-pointing indicator for immediate recognition.

Maintain consistent hover, focus, and active states across all interactive elements to ensure a cohesive user experience.

Badges for counts (e.g., number of countries) aligned right

Employ list semantics to structure the sidebar content, and utilize buttons with `aria-expanded` and `aria-controls` attributes for collapsible sections.

Implement keyboard navigation support including arrow keys for movement, Enter/Space for toggling, and Home/End for jumping between items.

Frequently asked questions

How should long lists be handled to avoid performance issues?

Long lists should be virtualized to efficiently render only the visible elements, minimizing heavy shadows and caching expansion states for toggle operations.
