RadixDropdown [example] v1.0.0

Radix DropdownMenu opens on click or Space/Enter, supports ArrowUp/Down for item navigation, ArrowRight to open submenus, ArrowLeft to close back to parent, Home/End to jump to first/last, and type-ahead (typing 'p' jumps to the first item starting with P). Supports separators, item indicators (check/radio), and disabled state.

Aesthetic Notes

• Trigger: standard button styling with a 12px chevron-down icon, 8px gap.
• Content: min-width matches trigger, white #FFFFFF bg, 1px solid #E5E7EB border, 8px border-radius, padding 4px.
• Item: 32px tall, 8px horizontal padding, 14px text, hover/highlighted bg #F3F4F6.
• Submenu trigger: shows chevron-right icon at right, opens on hover (300ms delay) or ArrowRight.
• Separator: 1px solid #E5E7EB with 4px vertical margin.
• Item indicator (CheckboxItem/RadioItem): 16px area at left for checkmark, label indented accordingly.
• Animation: 150ms slide-in from trigger direction (origin-top, scale 0.95 → 1).

What To Copy

• Type-ahead is the highest-ROI keyboard feature on long menus — Radix's default.
• Submenu hover-delay (~300ms) prevents accidental opens during cursor traversal.
• Use proper ARIA roles: role=menu, role=menuitem, role=menuitemcheckbox/radio with aria-checked.
• Animation origin should match the trigger direction — top trigger → scale from top, etc.

What To Skip

• Don't use DropdownMenu for navigation — it has menu semantics, not link semantics. Use NavigationMenu instead.

Screenshot Hint

Demonstrates

• Full WAI-ARIA menu pattern requires ArrowKey nav + type-ahead + Home/End.
• Hover-delay on submenu triggers prevents 'flicker hell' during diagonal traversal.
• Animation origin from trigger direction makes popovers feel anchored, not floating.
