I'm building a site that is looking to create a lot of different reallife experiences for people to go on.
In the right widget of this post I'd like to display under the Exclusive Experiences widget:
These would be drop downs.
Ie for instance if someone clicked on SPORT, tennis, motor racing and golf would drop down.
Then if they clicked on Golf, then the posts would be shown.
- Tennis (child)
- Motor Racing etc.
=> St Andrews (posts)
=> Ryder Cup
How do I do this?
