You know there is debug inspector in GOJS extensions. Thanks to it, we can show property of nodes or links. But I want to show combo box or anything else about form elements. How can i do that? I mean that property has options and selected one is showed. In fact this inspector can do it when it shows the default property of nodes. But the important point is data Properties. I want to add combo box to data Properties.
Data Inspector demonstrates how to implement a combobox to allow the user to choose a value for a property. Look for type: "select" and choices in the property descriptor.
We haven’t been improving the Debug Inspector, since people haven’t been using it.
You are great, thank you for your answer. I use it now and it works. But when i click the empty area in diagram, the inspector show null properties. Maybe it only shows black area, not null properties. Are there any solution for this?
