Good morning, maybe this is a stupid question, but I can't understand how to set a class style in the tab container properties, in particular in the `active, inactive and disabled`.  
The `style -> classes` properties is not present and if I try to add manually I can't make it work.

Thank you for the help

It's working for me on 8.1.41 without difficulty.

My procedure:

- Hit the + Add Object Member button.
- Select `value` from the dropdown.
- Type `classes` and press Enter.  
Now the dropdown arrow should appear and you can select classes as normal.

Thank you for your help.

I didn't try to add directly `classes`, I added `style` and then `classes`.

Have a nice day
