GOJS Tree Mapping :: Unable to pick the links

In GoJS, We are using tree structure mapping.

Not able to pick the links for delete purpose it works after several clicks and the same minimize not working properly due to not able to pick the point of minimize and maximize button.

Thanks,

Note how the link template is defined in the Flowchart sample: https://gojs.net/latest/samples/flowchart.html.

There are two Shapes that get the link’s route geometry, because they both have isPanelMain set to true. One has a transparent stroke, so it responds to mouse/finger events even though you cannot see it.

Note also how there are GraphObject.mouseEnter and mouseLeave event handlers on the Link template, to provide feedback to the user that the mouse is over that link.

For the other problem, are you talking about the “TreeExpanderButton”? If so, you could just make it bigger.
