Hi, I would like to know if HK supports out of the box parent-child drop-downs for product characteristics options.

For instance, I have a series of main options:
Opt1, Opt1, Opt3, etc.

Would it be possible to associate to the main options additional suboptions ie:
Opt1 --> Opt1.1, Opt1.2, ...
Opt2 --> Opt2.1, Opt2.2, ...

and have those suboptions displayed in a distinct drop-down next to the main drop-down once the parent option has been selected?

So far, I found the following reference:
