Group Controls do not work inside of repeaters! You'll have to use the standard Controls_Manager::COLOR for the background color.

Hello @bainternet, I am working locally. here you get the repeater code: https://pastebin.com/uiMHZ1vY

Hello @norewp, So how can i use gradient control? How can get this type of organize layout view: http://prntscr.com/htqbfy ?

@bdthemes

Like @norewp said, Group Controls don't work inside a repeater.

So in order to get the desired layout, you would need to add all tabs and controls manually.

But then again you can't have nested tabs, so I would suggest adding all fields required for all background types and only show them based on a select control which will hold the background type as a condition.

Hope this makes sense.
