I recently downloaded the jQuery responsive select menu for my site (which has a book lite theme) and I filled in the "Menu Container(s) Class / ID" box with two classes: .main-navigation and .main-small-navigation. The plugin's select menu completely works when I narrow my window to 800px width, which is what I set maximum width to. However, when I narrow in the window a few more hundred px, my theme's crappy default small navigation menu comes up again and replaces the plugin's select menu. I feel like the problem is about me not putting in all the necessary classes in the Menu Container Class box in the settings. I've tried each of the following classes to see if it would fix it, but none of them did: .site-navigation, #masthead, .menu-toggle, nav.site-navigation. Could someone tell me how I can get the plugin's select menu to stay there, no matter how narrow my browser window gets?

As you can probably tell, I'm a wordpress/css/php newbie so I greatly appreciate the help.
