Hey there, you can try two things:
- manipulate the active/collapsed/uncollapsed state of the groupboxheader
- wait for a moment and I will soon deploy a new module to the appstore in which you have a buildingblock for a groupbox.
For now i recommend you try point 1:
- inspect element to see which class you can manipulate
- change this within your custom.scss folder (theme > web > sass)
- it will probably look like this:
.collapsed{
.mx-groupheader{
background-color: //color;
}
}
The nyou can use the standard color for your uncollapsed styling and collapsed for your different styling
