Add button(s) to visualisation using javascript

[admin]

You can use Additional class to target certain elements. You can create labels using CSS (these won't be visible in the editor). This example uses three classes: obj1, obj2, obj3. Label position and other properties can be freely adjusted.

Code:

#widget-5 > div.item:after {
  position: absolute;
  top: -10px;
  left: 0;
  display: block;
}
.obj1:after {
  content: "obj1 label";
}
.obj2:after {
  content: "obj2 label";
}
.obj3:after {
  content: "obj3 label";
}
