Appreciate if anyone can advise on how to highlight the objects when the user hovers them.
The idea is that some Items need such effects (like lightening, changing color, or make bigger) to indicate these objects are clickable rather than keeping everything static.
Shapespark editor doesn’t allow to configure the hover effect. In the editor you can use some distinct, easily noticeable colors or icons to indicate which objects are clickable. You can also configure objects to rotate. Such indications have advantage that they work also on touch screen devices, which inherently do not support hover.
The only option available now to add hover is to use the JavaScript API as explained in this post.
