how do I make a div with a textbox inside drag, drop, and resize?

I need to have a div tag that has a label and textbox inside.  when I drag, drop and resize the div with the elements in it (label and textbox), the text box should resize with the div.  I have a somewhat working example  here  but the textbox is not resizing when I resize the div.  

Thanks in advance. George
