I am needing to create a custom taxonomy structure for my posts. I have read the WP Codex and am confident I can pull that off. My custom taxonomy will be hierarchical.
What I need to do is to create a filter based on this new taxonomy. I need to do this with drop down boxes.
Here is an example of my custom taxonomy will be:
— Article 1
— Article 2
— Article 3
— Amendment 1
— Amendment 2
— Amendment 3
What I need is to have 2 drop down boxes. The first one will have all of the top level categories (Articles, Amendments, etc…) and then when one of those is selected it will populate/make appear a second drop down with all of the subcategories.
How can I achieve this?
