Hi Aki,

We've done this in the past; not sure if I can find the source code for it, but I can give you the gist of it:

• You need to have a facet that gives you the list of Group IDs that contain results
• In the facet templates, you need to have an if statement looking for that special facet system name
• When you're rendering that facet, you need to render the group navigation instead and then check against the loop of options to determine if there are results. If there are, show the number of results or 0
• When rendering the group name, you need to render the markup to look like a tree view, but submitting the checkbox as if it was a regular facet option

Does that make sense?

Hi,

Thanks for the input. Yes it makes sense. 

I started with the approach to create a groupnavigation that behaves like a facet when clicking the nodes but your way sound better.

Hi again Nuno,

If you happened to find the code, feel free to send it. And I'll buy you a drink at the next summit. :)

Hi Aki,

No such luck, sorry
