Navigation Menu Button: Inaccessible
- Only tab keyboard support
- Menu button pattern requires the links to act like a menu, which included supporting the cursor keys.
- Menu button pattern requires the tab key to close the menu and move to next focusable item on page.
- If only tab key is support, the disclosure pattern should be used instead of the menu button pattern.
- No description of behaviors to assistive technologies.
- Poor keyboard focus styling.
