I'm currently working on a project where i want that my user can place marker on a blueprint (PDF, image, anything that would work). Then they fill out a form that is connected to that marker. A second user must be able to see the markers and see the form when clicked on.
Lets say they find a problem in a building and they want to document this problem on the location where is was found. Then another user must be able to see those markers and resolve them.
The problem is that i have no idea how i can make it possible for my users the place markers and save them the right way.
