I think I did something similar to what you want at http://bluegrassmiataclub.com/. See the Events->Event Talk, and Ads and More ->(all subtopics).
It turned out to be a fair amount of work, but here is an outline.
- Set up a Static Front Page.
- Create a template to display a single category. I had to code my own because I could not find one that handled 'sticky' posts. I used a custon field in the page to specify the Category of the posts to display on that page.
- Create the Categories you need - 'Music' and 'Dance' and assign them to the respective posts.
- If you want to restrict navigation to only posts in the same category when someone views a post, you will need to create a modified single.php.
To make a long story short, I had to do quite a bit of coding. It may be possible to find plugins to do similar work, but none I found did exactly what I needed.
I will share my code with you if you wish. You can contact me using the About->Contact Us form on the BluegrassMiataClub.com site. Just select Webmaster to contact.
