Hello. Can you help me?
i need more than one parent category for category (like product have many categories)
Ex:
Category 1
subcategory 1.1
subcategory XZ (multy parent)
subcategory 1.2
Category 2
subcategory 2.1
subcategory 2.2
subcategory XZ (multy parent)
Its can be done?
If this is only for display, you can create a module, where you can select the sub categories to display.
But if course, because a category need always same parent in real, the breadcrumb display certainly the real parent
So you can display it so, in a module and using fake menus link, but in real, you can have many troubles about the links.
