This plugin came about because for once I couldn’t find a plugin that already had this functionality for WordPress, so I thought it should be 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, so if you wanted 3 levels of categories to show you could use the template tag as (by default it will always show 2 levels of categories if no value is past):

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 stright into your posts & pages. In the meantime if there are any plugin developers out there that would like to help me develop this plugin then please do get in touch.

The plugin is now live on WordPress.org and is called Category Ajax Chain Select.

PLEASE BEWARE THIS PLUGIN WILL ONLY WORK IF YOU ARE USING %category% IN YOUR PERMALINK
