Many sites have dropdown menus where the expanding of the links can only be triggered by a mouse hover. This means that for keyboard only users parts of the site are harder or sometimes impossible to reach.
This plugin makes these dropdown menus keyboard accessible. When tabbing through the primary navigation the sub level menus will become visible and users will be able to tab to the lower level links.

How it Works:
Using the script, whenever a link in the menu gets focus its containing list item (

- Will this work with any theme?
We can’t guarantee that it works in all themes, but it now works with many more than in earlier versions. It has been tested in Twenty Ten through Twenty Thirteen, themes based on Automattic’s Underscores base theme, and a number of others. The plugin looks for the “navigation” ARIA role rather than any particular ID, so it should work in most themes that correctly implement roles.
- What about child themes?
If the plugin works in a parent theme, it should work in child themes based on that parent. However, because of the nature of child themes, this cannot be guaranteed.
