♿ Screen Reader Test

+

+ These dropdowns have proper ARIA attributes and labels for screen readers: +

+
    +
  • role="combobox" identifies as dropdown
    • +
  • aria-haspopup="listbox" indicates popup type
    • +
  • aria-expanded shows open/closed state
    • +
  • aria-label provides accessible name
    • +
  • Selection count announced to assistive technology
    • +
+
+ +
+
+ + +

+ {{ selectedColors.length }} color(s) selected +

+
+ +
+ + +

+ {{ selectedSizes.length }} size(s) selected +

+
+
+
+ ` + }) +} + +export const FocusManagement: Story = { + render: (args) => ({ + components: { MultiSelect }, + setup() { + const selectedItems = ref([]) + const focusTestOptions = [ + { name: 'Option A', value: 'a' }, + { name: 'Option B', value: 'b' }, + { name: 'Option C', value: 'c' } + ] + + return { + selectedItems, + focusTestOptions, + args + } + }, + template: ` +
+
+

🎯 Focus Management Test

+

+ Test focus behavior with multiple form elements: +

+
+ +
+
+ + +
+ +
+ + +
+ +
+ + +
+ + +
+ +
+ Test: Tab through all elements and verify focus rings are visible and logical. +
+
