@informatix8/access-dropdown v1.2.0

Access Dropdown

Auto-positioning accessible dropdown.

Examples and the API are in the documentation.

Features

• Auto-positioning with requestAnimationFrame: the dropdown tries to stay on screen
• Click outside to dismiss
• Press Esc to dismiss
• Click the X to dismiss on small screens
• When focus finally leaves the dropdown’s content when using Tab, the dropdown is dismissed
• Inline styles can be disabled
• After dismissal, focus is returned to the last focused element or a designated element
• Pre and post user defined functions can be called during significant events
