This plugin came about because I couldn’t find a plugin that already had this functionality for WordPress, so I created a simple plugin to get me going. At present it is very basic; using a template tag below, you can place the chain selects any-where on the your page template, and then style it using CSS.

chainselect_getcategories();

The plugin also has the ability to pass the category level through, for example if you wanted 3 categories visible, you could use the template tag as (by default it will always show 2 category levels if no value is passed):

chainselect_getcategories(3);

I will continue to work on this plugin over time and add new features such as page codes, so that you can add the select boxes straight into your posts & pages. In the meantime, if there are any plugin developers out there that would like to help me develop this plugin, I’d love to hear from you.
