I'm looking to create a Django site that has a diagrams.net (drawio) diagram such as a flowchart. When a user clicks on one of the symbol-boxes I want:

For desktop browser: a sidebar to pop-in from the right side that would contain content relating to that box.

For mobile: perhaps a pop-down which, when a symbol is clicked, a window draws open from the mid-screen to the bottom with the dynamic content.

I'm more concerned about the first item. It's going to be tricky for users on mobile but, I do need to deliver content there as well. I do realize this will likely take two entirely different approaches.

Thanks!
