 Although this may be a somewhat trivial and silly use of category widgets,
 currently placing two category widgets onto the same page with the
 dropdown option set results in having duplicate javascript and duplicative
 identified select boxes.

 Whilst the instance of each widget is unique, the select boxes displayed
 at not given unique IDs or Names, resulting in valid markup, and resulting
 in only the secondary select box operating correctly. The JS var gets
 redeclared by the duplicative script, which gives precedence to the second
 dropdown.

 One use case would be a page that lists long archives and shows a jump
 menu at both the top and bottom of the page. This would have to be done
 directly in the template due to the widget restrictions at present.

 I am attaching a patch that adds a static counter into the category widget
 function, and gives each dropdown a unique identifier ID/Name, allowing
 simultaneous use of several category dropdowns, the JS function is updated
 appropriately to.

 Code tested on IE7 and FF3, functionality remains the same as the original
 code, minus the limitation mentioned above.

 Feedback is appreciated, and please do re-tag if necessary.
