dropOntoLink function will be called only when we place mouser pointer on that link. Let me tell you clearly,
In the first image you can see that I am trying to drop a node on link but I am not able to drop.
In the second image you see that I am able to drop only after the mouse pointer placed on link.
mouseDragEnter, mouseDragLeave, mouseDrop all the functions will be called only after the mouse pointer touches link(like image2).
So, My Question is Can I drop new node on link and make the link split when new node actually touches link(like image 1)?
Even I have tried Custom Dragging tool methods doDropOnto&doDragOver all these works after the mouse pointer touches the link(like image2). I need to drop a new node on link like image1 shows.
