Moveable & Resizeable PromptWindow

[Silvester751]

Hello
Is there a possibility to get a value prompt moveable and resizeable?
I have following: On my Report Page is a promt inside of a block
Above the prompt are two html items with

<script>
function ShowReportOptions3() {
floaty = document.getElementById('floating_pane_ug')
floaty.style.display = 'block'
floaty.style.left = 50
floaty.style.top = 450;
}
function HideReportOptions3(){
  floaty = document.getElementById('floating_pane_ug')
  floaty.style.display = 'none'
}
</script>

<a href = "javascript:" onclick = "ShowReportOptions3()">Neue UG</a>

AND

<style>
.float_tree{
padding-left: 10px;
padding-right: 10px;
background-color: #efefef;
position:moveable;
display:none;
border-style:groove;
border-width:4px">
}
           }         
</style>
<div id= "floating_pane_ug" class= "float_tree">


BELOW the prompt is just a HTML item with </div>

So if you run the report you can click on a link and the prompt will be shown at a spezific position.

I want to move the prompt with the mouse and if its possible resize it.

Any answers?
Regards Silvester
