Jumbo v3.8 – A 3-in-1 full-screen menu for WordPress Plugins

Jumbo is a WordPress menu plugin that you can add to any theme, and it comes with a bit of a unique twist. Next to allowing you to build a bold, memorable and fully responsive full-screen menu, you can also create an optional, secondary drop-down menu.
