I'm working with the awesome select2 control.

I'm trying to clean and disable the select2 with the content too so I do this:

$("#select2id").empty();
$("#select2id").select2("disable");

Ok, it works, but if i had a value selected all the items are removed, the control is disabled, but the selected value is still displayed. I want to clear all content so the placeholder would be showed. Here is a example I did where you can see the issue: http://jsfiddle.net/BSEXM/

HTML:

<select id="sel" data-placeholder="This is my placeholder">
    <option></option>
    <option value="a">hello</option>
    <option value="b">all</option>
    <option value="c">stack</option>
    <option value="c">overflow</option>
</select>
<br>
<button id="pres">Disable and clear</button>
<button id="ena">Enable</button>

Code:

$(document).ready(function () {
    $("#sel").select2();

    $("#pres").click(function () {
        $("#sel").empty();
        $("#sel").select2("disable");
    });

    $("#ena").click(function () {
        $("#sel").select2("enable");
    });
});

CSS:

#sel {
    margin: 20px;
}

Do you have any idea or advice to this?
