title: How to collapse the leaflet control
body: <p>I start my application with expand Layer-Control:</p>
  
  <pre><code>L.control.layers(baseMaps, overlays, { collapsed:false } ).addTo(mymap);
  </code></pre>
  
  <p>I found no Mouse-Action to minimize the Layer-Control. I want to minimize the Layer-Control. But I don't know the handler. Could anybody give me a tip?</p>
