Collapse mobile menu on Catch Reponsive Pro

I have a lot of menu items on my website. It is fine on a computer screen because the second and third level menu items do not show up until I hover over the top menu item. However, on a mobile device, all the menu items show up on the left (every item is visible at the same time). Is there a way to set the menu items to collapse and expand so the list isn't so overwhelming to look at on a mobile device? Do I need a specific plugin for that? Thank you!
