Move label

Hi,
I have developed diagram similar example http://gojs.net/latest/extensions/BPMN.html .
I have problem with label in link elements. Is it possible to move these labels?

Thanks,
Giuseppe

Did you want to let your users move the labels manually? If so, use the Tool demonstrated in http://gojs.net/latest/extensions/LinkLabelDragging.html. It is defined in http://gojs.net/latest/extensions/LinkLabelDraggingTool.js, which you can load and install as shown in the HTML sample page.
