Hey all,
I'm guessing I won't find the answer here, but I'll try it anyway:

I'm editing a website, and this site uses data-groups, of which I'm not familiar (enough) with.
Example:
*category = groceries
*subcategory = drinks
*subsub(?)category = soda

(Sorry, since the site thinks I post spam, I need to put my question in an image here)

On the page, there's a button which displays "Drinks". When clicked, all the items in this category appears.
I can find the subcategory back in K2/categories, (Groceries > Drinks).

However, I now need to make a dropdown with more sub(sub)categories. So in K2/categories, I make one called "Soda". But no matter what I do, a button with <li class="active" data-group="Soda"> does not work.

How do I get this to work?

so if I want to place a subsubcategory under the subcategory, I would place
<ul><strong>Tools</strong>
<li class="force-css" data-group="Soda"><a href="#">Block 1</a></li>

but that doesn't do anything. What am I supposed to type there? Nothing seems to work...

In other words, how do you make a subsubcategory, and what do I type in its data-group tag?
Do I need to add php or js somewhere to make it work?

Well this is useful.
