im not a very good developer and i need to make diagrams with (many) customs elements from mysql db and sort them in dropdown list (example below).
Is it possible to modify bpmn to do that ? is it easy, hard, very hard, impossible ?
If its not possible, maybe can someone give me advices for another library ? thanks !!
Bpmn-js is easily customizable.
Have a look at here to see how custom elements can be created.
For diagrams not related to BPMN you can use diagram-js.
