title: Clickable L.control on leaflet
body: <p>I am trying to add a <code>L.Control</code> element to my leaflet map. 
  However once I added the element to my map, I noticed that its not <code>clickable</code>. I would like to display a form inside this <code>L.Control</code> element, however I cant select any elements from my drop down menus, since the clicks always go through to the map.</p>
  
  <p>Here a JSfiddle: <a href="http://jsfiddle.net/fd3dnnc1/1/" rel="nofollow">http://jsfiddle.net/fd3dnnc1/1/</a></p>
  
  <p>as well as my JS code:</p>
  
  <pre><code>var map = L.map('map').setView([0.27, 37.66], 6);
  
          // add an OpenStreetMap tile layer
          L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
          attribution: '&amp;copy; &lt;a href="http://osm.org/copyright"&gt;OpenStreetMap&lt;/a&gt; contributors'
          }).addTo(map);
  
  
          var mainMenu = L.Control.extend({
                  options: {position: 'topright'},
  
          onAdd : function (map) { 
                  this._div = L.DomUtil.create('div', 'mainMenu');
                  this._div.innerHTML =  '&lt;h3&gt;Main Menu&lt;/h3&gt;';
  
          this._div.innerHTML +=  '&lt;h4&gt;Data:&lt;/h4&gt; MODIS NDVI &lt;h4&gt;AOI:&lt;/h4&gt; Kenya, Africa &lt;br&gt;&lt;br&gt;'
          this._div.innerHTML +=  '&lt;h4&gt;Indicator:&lt;/h4&gt;'
          this._div.innerHTML +=  '&lt;form&gt;&lt;form id="form" class="form" action="" method="POST"&gt;' +
                          '&lt;select name="indicator"&gt;&lt;option value="NDVI_ABS"&gt;NDVI&lt;br&gt;' + 
                          '&lt;option value="NDVI_VCI"&gt;VCI&lt;br&gt;' +
                          '&lt;option value="RAIN_ABS"&gt;Precipitation&lt;br&gt;' +
                          '&lt;/select&gt;';                        
          this._div.innerHTML += '&lt;input type="submit" value="Refresh Map"  name="submit"&gt;&lt;/form&gt;';   
          return this._div;     
                  },                                  
          });
          map.addControl(new mainMenu());
  </code></pre>
  
  <p>Any suggestions on how to make it clickable?</p>
