Sub-Menu in Mobile View

Hello,

When I view my page through the mobile version, you have to click the main heading, and then scroll down there to view the sub-menus.

Is there a way with this theme to have the sub-menus automatically show up under their main menu, just tabbed over to indicate they are a sub-menu?

Current site: mrcllc.us (Header menu is Residents, need its sub-menus to show up in mobile version).

Thank you.
