Lets say I have the following Categories in WordPress:
Product Category – Cat A – Cat B – Cat C
Service Type – Service A – Service B – Service C
On the Manage Posts page on the Admin side, I want to have 2 drop down filters for both Product Category, and Service Type, so I can filter by both on the backend.
How can I do this?
I’d say it’s quite a huge task to split the default taxonomy in two dropdowns. Maybe some wizard stumbles upon your question and enlighten us…
The biggest problem I see is the split itself, because you can modify the query
&cat=1to&cat=1,25so as to list two categories (by their id’s).What I suggest is creating a custom taxonomy for dealing with either Products or Services. And leave the other in the default categories.
And then apply the solution I linked in the comments to the question.
This way is easy to have two dropdowns and do the custom filtering you’re looking for.
Just tested and it works.
Hope this helps.
