Has anybody done this, if so could you share the coding:

I'd like to place a drop down selection on the Links pages at the top right (using the luna template) of the yellowish colored strip, that has a drop down selection list of all the main categories and a "go" button.

When someone chooses a category, and presses the go button, they will be directed to that particular static category page.

I don't know if I should be looking for something like this that would need javascript, or if it would require a back end cgi or php script to process the form or not. Hence why I ask if someone else has already done this and wouldn't mind sharing the code, please do. No point reinventing the wheel so to speak.

Thanks,
