I have a list with the following markup:

```
<div id="myList">
    <div data-role="collapsible">
            //...
    </div>

    <div data-role="collapsible">
            //...
    </div>

    //...

</div>

```

If I want to remove the first X (X is a specific number) childs of the list, which selector can I use in the following statement:

```
$("#myList").remove("???");

```
