title: ng-show/hide but with Bootstrap's collapse effect
body: <p>We're using Angular and Bootstrap (note: but not Angular UI Bootstrap). I have a <code>div</code> with an <code>ng-show</code> on it. What I don't like is that when it shows or hides it doesn't exhibit a collapsing, like you see with Bootstrap's collapse. How can I get this growing/shrinking behavior that collapse uses to work with ng-show? Like, I when ng-show is true, I want to see the element collapse-show. And when ng-show is false, I want the element to collapse-hide.</p>
