Can we Html.Listbox for draggable?

Question

Basically, I'm using Html.Listboxfor with 'MultiSelectList' options. The trouble I have is, I want the listbox to expand as per the length of the text within that listbox. I'm using following style, any inputs to make this happen??

display: inline;
  width:100%;
  height: 34px;
  padding: 6px 12px;
  /*float: left;
  clear: left;*/
  font-size: 14px;
  line-height: 1.428571429;
  color: #555555;
  vertical-align: middle;
  background-color: #ffffff;

Alternatively, if I can provide drag option where users can drag the list box to see the full text width, that would be beneficial too.

Any help is appreciated.

Thanks.
