SelectPanel

A SelectPanel provides an anchor that will open an overlay with a list of selectable items, and a text input to filter the selectable items

Example

function getColorCircle(color) {
  return function () {
    return (
      <Box
        borderWidth="1px"
        borderStyle="solid"
        bg={color}
        borderColor={color}
        width={14}
        height={14}
        borderRadius={10}
        margin="auto"
      />
    )
  }
}

const items = [
  {leadingVisual: getColorCircle('#a2eeef'), text: 'enhancement', id: 1},
  {leadingVisual: getColorCircle('#d73a4a'), text: 'bug', id: 2},
  {leadingVisual: getColorCircle('#0cf478'), text: 'good first issue', id: 3},
  {leadingVisual: getColorCircle('#ffd78e'), text: 'design', id: 4},
  {leadingVisual: getColorCircle('#ff0000'), text: 'blocker', id: 5},
  {leadingVisual: getColorCircle('#a4f287'), text: 'backend', id: 6},
  {leadingVisual: getColorCircle('#8dc6fc'), text: 'frontend', id: 7},
]

function DemoComponent() {
  const [selected, setSelected] = React.useState([items[0], items[1]])
  const [filter, setFilter] = React.useState('')
  const filteredItems = items.filter(item => item.text.toLowerCase().startsWith(filter.toLowerCase()))
  const [open, setOpen] = React.useState(false)

  return (
    <SelectPanel
      renderAnchor={({children, 'aria-labelledby': ariaLabelledBy, ...anchorProps}) => (
        <Button trailingAction={TriangleDownIcon} aria-labelledby={` ${ariaLabelledBy}`} {...anchorProps}>
          {children || 'Select Labels'}
        </Button>
      )}
      placeholderText="Filter Labels"
      open={open}
      onOpenChange={setOpen}
      items={filteredItems}
      selected={selected}
      onSelectedChange={setSelected}
      onFilterChange={setFilter}
      showItemDividers={true}
      overlayProps={{width: 'small', height: 'xsmall'}}
    />
  )
}

render(<DemoComponent />)

Accessibility

Keyboard

Pressing Enter or Space on the SelectPanel anchor will open the SelectPanel and place focus on the filter input. Pressing Escape or interacting with the cancel or close buttons will close the SelectPanel and restore focus to the anchor.

A user may use Tab and Shift+Tab to navigate between the filter input, list of items, action buttons, and the close button.

When focus is on the list of items, pressing ArrowDown and ArrowUp will allow navigation between items. Support for Home and End is also provided to quickly navigate to the first and last items in the list, respectively. Pressing Space will select an item.

The Enter key may be used when focus is within the SelectPanel as an alternative to activating the save button.
