     /**
28 |  |
      * This class is for generating a SelectorBox. It is good when used
29 |  |
      * with WM because you can stuff it into the context and then just
30 |  |
      * call it to generate the HTML.  It can be used in other cases as
31 |  |
      * well, but WM is the best case for it right now.

      * <p>For example code showing the usage for this module, please see
34 |  |
      * the toString() method below to see how it would be refered to from
