Can I make an input form sortable?

Question

I can use jQuery UI to make an ul sortable. I can do the same with a group of divs. This means that each item can move and change position.
1- It seems that it is not possible to do a form sortable, is that correct? 2- One solution I tried is to put each form input inside a li or a div. But, is this the best way to do it?

JQUERY:

$(function() {
    $('#sortable').sortable();  
});

HTML:

<ul id="sortable">
    <li id="1">item1</li>
    <li id="2">item2</li>
    <li id="3">item3</li>
</ul>

<form id="sortable" action="extern.php" method="post">
<input type="text" id="item1" name="item1" value=""  ><br>
<input type="text" id="item2" name="item2" value=""  ><br>
<input type="text" id="item3" name="item3" value=""  ><br>
</form>

Sortable() has an option named cancel with the default: "input, textarea, button, select, option" that prevents sorting if you start on elements matching the selector.

$("#sortableList").sortable({ cancel: null });

And you should be good.
