title: ASP.net control similar to auto-hide feature of Visual Studio toolbox
body: <p>First off, I'm sorry if the title doesn't explain this very well. </p>
  
  <p>I'm looking for an asp.net control that works similarly to the Visual Studio toolbox's auto-hide. In other words, when not needed, it can be "unpinned" and will slide off to the side of the screen. When needed, it can be opened and pinned to stay in place. I'd rather not do it myself using javascript if a (free) control already exists. Does anyone know of such a control? If not, has anyone implemented this type of functionality using a js library with good results? Any pointers?</p>
  
  <p>Thanks in advance.</p>
