Bestia theme has a nice feature in menus called flyout content which one gives a beautifull look and opens a list of performers, channels or categories on mouse over.
Lets start steps one by one.
We have to go in WP-Dashboard > Appearance > Menus to enable the css classes which is required to use this feature.
Screen options are on the top right side of menus page.
Scroll the page down and go to the menu items. The css classes to add are:
flyout-performers = Opens the performers window on mouse over.
flyout-channels = Opens chanels list window on mouse over.
flyout-categories = Opens categories list window on mouse over.
After adding the css classes you have to activate jquery for each menu item in theme settings panel > taxonomies tab
