[Solved] Wayfinder -> How to show container only?#

Hi, this is my first post.

I want to show a navigation which show every container (only container) under a resource. How can I achieve that with wayfinder?

Some container may have children or not.

&level is not an option because a container may have different depth,
Using Hide from menu also not an option.

Edit:
========

Solved by adding a new parameter, I called it &folderOnly. It still needs testing though
Modified wayfinder.class.php attached

========

Thanks,

dvio

Not sure exactly what you were doing but you can specify either a class name or custom row template for resources that are a container:

Always better to try that first than to make code changes - it can be difficult to track what you've changed and then wonder why everything breaks when you upgrade some time later

I introduced a new option &folderOnly and add1 to the getData query.

the modification is here

I don't know if it's the right way or else, but it's work for me.

@Lucas thank you, yes I have tried the class and the template option, but I don't want to add extra function in the template since I will have a lot of resource, and I'm afraid it will affect the performance, will it?

Anyway, I'm using &where=`{"isfolder":1}` right now (while waiting the parameter to be added to the master (I hope))

I think using &where=`{"isfolder":1}` is saver and performance friendlier

the call example:

Thanks for sharing that the 'Where' clause works with Wayfinder! Saved me heaps of time trying to solve the exact same thing.
