<p dir="auto">Bootstrap's hierarchical menus are a lot like Mac OSX, i.e., broken. I'd like to suggest two changes that would greatly improve usability:</p>
<ol dir="auto">
<li>Don't hide the menu when you click on a divider or bottom/top padding.</li>
<li>Implement mouse movement tracked submenu display, like the one invented by Apple in the 80's and currently used prominently in Amazon's homepage. More info <a href="http://bjk5.com/post/44698559168/breaking-down-amazons-mega-dropdown" rel="nofollow">here</a>.</li>
