There are 2 menu systems
– On the left Barcelona / Spain
– On right : Highlights | Things to do and so on
The beauty is If pull down Barcelona and select El Raval, then Highlights and Things to Do etc relate to El Raval
and so on.
Can I implement a similar menu structure. If yes, which product do I need to use?
If I am understanding correctly, it seems like you would have a menu structure where the top level items were all the locations/cities.
Then under each city, there would be children (things to do, highlights, etc).
The menu on left in this example would be a standard wp_nav_menu with the depth set to 1. The menu on the right would use my plugin to set the start_depth to 1 so that it only shows the children of the active parent.
You would of course need to figure out the CSS/JS to get the look and interaction that you want out of the two menus, but functionally it is pretty straightforward.
