WordPress WooThemes’ Canvas Mobile Menu Addition. Hides sub-menus in mobile mode and shows them only when clicked.
This will add the display:none property to all sub-menus so that only the top-level menus are shown in mobile mode.
When the top-level menu is clicked it will show the sub-menus below it. If you click on the top-level menu a 2nd time it will route to the top-level menu URL destination.
This plugin works recursively, so this will allow sub-menus which have sub-menus within them to behave the same way.
**There is also sometimes a CSS glitch if you leave the menu open in mobile mode and then resize the window to a another mode, this plugin fixes that issue by closing the menu whenever the width is resized.
Requires WooThemes Canvas theme or child-theme.
