I have an issue with categories with different levels:
I have a group of categories which have a structure like this:
First form: 1.0 Group – 1.1 Subgroup – 1.2 Items in subgroup
Second form: - 1.0 Group – 1.1 Items in Group
In some groups are subgroups in others aren't. But I need to list all the items, regardless if they are in a subgroup or not. How can I adress them correctly. Can I do an if statement like: if there is no 1.2 level, take the 1.1 level and treat it like a 1.2 level?
How can I do this?
