Template:Listbox2

Usage
This template allows you to (in order): All variables are mandatory.
 * 1) specify the width of the listbox.
 * 2) specify the margin on the left side of the box. (you can use em, px, or %)
 * 3) specify a color in any form; #hex, color, rgb.
 * 4) specify a title.
 * 5) define the contents of the listbox.

This version differs from the other in that you define the width. You need to specify if you want 200px or 20% by using the appropriate format.
