In general we want to help users by making sure that they are on the right track regarding the user of our tools.
Does the following apply to you?
- You have an underlying BPMN 2.0 diagram
- You would like to add cloud-shaped custom element to it
If that is the case, checkout our freshly updated custom elements guide. Custom elements created this way have direct editing support, out of the box.
If you need full customizability (via bpmn-js-example-custom-shapes), look into our default LabelEditingProvider for inspiration. That one sets up label editing for BPMN shapes. You’d need to roll your own for your custom elements.
Hope that helps you!
