Newbie here. I would like to create something where I choose out of the exisiting instances or create a new instance of the structure from a dropdown menu. In my project I create different participants and I have another structure which is called clause which references exactly one participant. What I would like to do is that when I get to the participant field in the clause strucutre that there appears a dropdown menu (i dont know what language i have to import to get the dropdown or what I would have to do) with the already existing participants plus a "create a new participant" field. If the user selects the "create a new participant" field there should automatically be a new participant created where i could enter the name and the name in the clause should automatically update itself.
Thanks in advance.
