I'm building a module with a dashboard using bootstrap. I added a setting to the module to determine if the skin uses bootstrap so the module doesn't need to add the bootstrap.css and bootstrap.js files.

When the skin doesn't use bootstrap the module adds the css and js to the page. This works fine but i have a problem with the menu which disappears. 

I use the default DNN Gravity skin.

Can anybody tell me how to make sure the menu doesn't disappear when my module adds the bootstrap.css.
