Dropdown list

Variants and Usage

  • default - Used as base for other dropdowns
  • with-breakpoint - Used in: Footer
  • secondary - Used in: Filters
  • with-nested - Used in: Sidebar
  • inner - Used in: with-nested
  • detailed-content - Used in: Minicart (to do: name change?)

Accessibility:

  • Buttons (reactive elements, which open dropdown) should have following aria attributes:
    • aria-expanded - set to true if dropdown field is open, to false when it’s closed
    • aria-controls where value it’s an id of content dropdown element
  • Dropdown content should have aria-hidden attribute set to true of it’s closed and to false when it’s open.
  • focus management and keyboard support should be implemented
