只需使用 this 提示.它从地图容器中删除 L.control 元素并将其添加到新的父级.您可以直接对侧边栏执行此操作.

Just use this hint. It removes the L.control element from the map container and adds it to a new parent. You can do this for the sidebar straight forward.

HTML:

 <div id="sidebar" class="sidebar collapsed">
   <div class="sidebar-tabs">
    <ul role="tablist">
     <li>....</li>
     <li>....</li>
    </ul>
 </div>
 <div class="sidebar-content">
   <div class="sidebar-pane" id="">  
    <h1 class="sidebar-header">...</h1>
    <div id="example"> <!--Here the layer control menu will be added--></div>    
 </div>
</div>

JS:

var layer = L.control.layers(baseMaps, overlayMaps).addTo(map);

  var htmlObject = layer.getContainer();
  var a = document.getElementById('example')
  function setParent(el, newParent){
    newParent.appendChild(el);
  }
  setParent(htmlObject, a);

对我来说，这个解决方案效果很好.

For me, this solution worked well.
