Need to create links from elements in a drag & drop fashion, but only show the connect tool when a user hovers an element path? When the user hovers an invisible track path on an element, the tool appears at the point where the user moves the mouse.
Hover the element path, in this case the body, and see how the hover connect tool appears. Click on the track path to create a link.
