Hello everyone.
I've been trying recently to create a view with a multi-state button with icons instead of text, as shown here:

But I can't seem to find any way of inserting an icon, as is possible with the 'image' property of a regular button. Is there perhaps a way around this or another option\method for multi-state buttons?
Thanks in advance 
Try using background images:
states.0.selectedStyle.backgroundImage : url("/system/images/path-to-image.svg")
and do the same for
states.0.unselectedStyle. ...
Repeat for each button option.
Use Tools | Image Management to upload the icons.
If I was to use your application I'd surely appreciate tooltips on your icons. I have no idea what they might mean. The problem is that there is only one tooltip for the whole multistate.
