I am working on JointJS API. However I want to prevent the elements from being movable from their original positions. Can you suggest me some feature of JointJS or any feature of CSS in general, which I could use to make my object immovable. I can't use interactive: false option on the paper or paper.$el.css('pointer-events', 'none'); because I need to have highlighting features when mouse hovers over the element. Please suggest a way that disables movement of elements while allowing other features.
