[jQuery] UI/Resizable

[nos]

hi
I  applied  the resize option to resize a textarea's height while the
width should be dynamic (100%), so if the user resizes the browser
window the textarea changes it's size.

The default behavior seams to be that the width changes to a fixed
value. Anyone an idea how to change that?
thanks for any hints

  $(".resize-y").resizable({
    handles: "s,e",
    preventDefault: true
  });
