Hide dropdown pages in mobile menu

Hello, I am using Catch Everest free version and I really love the theme. However, the mobile menu shows all the dropdown pages. Is there any way to hide these in the mobile view so it is not so cluttered? I have been searching for an answer and saw some suggestions in a Catch Flames forum post, but it did not work. Any advice would be greatly appreciated! Here is the link: http://webg1rl.com/karenmorganimages/ Thanks! Heidi
