Of course this is not possible at the moment using the dropdown_cats function as it creates the <select>, therefore preventing me from adding the onchange attribute. It also sets the value attribute of each option to it’s index rather than the category URL which is required for changing the window.location.
Has this type of functionality been considered before?
Moshu, I edited my original post before you replied I think. If you re-read you’ll see my comments on the dropdown_cats function. I know I can do this myself with code changes but I think this would be a useful addition to the codebase.
