ComboBox组件中实现下拉树效果:

        triggerAction:'all',

        tpl: "<tpl for='.'><div style='height:200px'><div id='tree'></div></div></tpl>",  
        selectedClass:'',  
        onSelect:Ext.emptyFn  
    });  
    var tree = new Ext.tree.TreePanel({  
        loader:new Ext.tree.TreeLoader(),
        border:false,  
         root:new Ext.tree.AsyncTreeNode({text: '目录',id:'0'}) ,
         listeners:{
           beforeload:function(node){
                   this.loader.dataUrl = '../../nodes.action?ID=' + node.id;
           }} 
      });  
      tree.on('click',function(node){  
          combtree.setValue(node.text);  
          combtree.collapse();  
      });  
    combtree.on('expand',function(){  
        tree.render('tree');  
      });  
    combtree.render('combtree');
