Need a guided horizontal line on drop a html task on node text

Hi team,

we have to implement a guided horizontal line on drop task in b/w two text (on mouse enter on textblock this guided line should be visible) here is a pictorial representation of what we want…!

Here when I drag a task in b/w textblocks(b/w select task and save process) than this horizantal guided line should be visible to indicate that dragged node will get dropped in b/w these two text.

So, suggest me some example or customization through which we can achieve this functionality in our diagram.

It depends on how you implemented those objects: “Select Task”, a down arrow, and “Save Process”.

One common approach is to implement GraphObject.mouseDragEnter and mouseDragLeave event handlers to show and hide that horizontal line.
