Adding search to the menu

I tried putting <?php get_search_form(); ?> after <?php cryout_access_hook();?> and before </nav> in the header.php of my child theme, but it messes up the drop down menu function. The search form shows up in the menu and works, though.

How can I get the search form to show up in the menu without it interfering with the drop down menu item and menu links on the top/main menu?
