JavaScript
Drag and drop link creating is enabled by default (linkCreateHandling="Update").

The linking points are activated on task hover. You can create a new link using drag and drop.

In addition to the default action specified by linkCreateHandling, two events are fired:
- onLinkCreate (before the default action)
- onLinkCreated (after the default action)
You can add a new link using links.add() method.
Example
Drag and drop link creating handler.
gantt.onLinkCreated = function(args) {
gantt.message("Created");
};
Adding a new link using JavaScript
gantt.links.add({
from: "1",
to: "2",
type: "FinishToStart"
});
