summary: A category dropdown (select list) in WordPress
---

[WordPress][] provides a [template tag][template], [wp_dropdown_categories][cat], that inserts a drop-down list (the HTML <select> element) of categories, where the value of each item is the ID from the database. This works fine if you are not using rewrite rules (AKA "pretty links") - you can construct a URL using the value (?cat=[number]). However, if you use any sort of rewrite rules, this does not work. I recently converted my [personal site][], which uses the Pool theme, to utilize a JavaScript array to assist with displaying category pages.

Here's the code...

_Edit: Code has been moved to [this post][]._

This works for both "pretty" and standard links, as it uses the template tag [get_category_link][link] to specify the link.
