     <option value=""></option>
     <option value="1">Column 1</option>
 </select>

```

select2me class for select2 jquery plugin.

Answer: 
You need to initialize select after success callback, because your drop down is added dynamically in DOM,

```
success:function(res){
   $('#colpart').find('.portlet-body').html(res);
   // reinit your plugin something like the below code.
   $('.select2me').select2();
}

```
In the ajax success function you need to initialize the select.

Example:

```
    success: function (html) {
        // your code here
        $(".select2").select2(); // init the select
    }

```
