Making items draggable in a form

[jbadiag]

Hi, I have a form where I want to make some items draggable.
I made a js file in components->fabrik->js with the name of the form and I want to include the wollowing jquery code:

alert("hoo");
$( function() {
    $( "#imatges___ordre_0" ).draggable();
  } );

But I can only view the alert. How can include jquery elements?
Thanks

Replace '$' with 'jQuery''.

Thanks.
Does not work. I used

alert("hee");
jQuery( "input" ).draggable();

May I have to implement another version of jquery?
In this website there's an example

Try with another element.
The code work for me.
