Creating a list

I want to create a list of “Memos for the population”
A list of “MEMOS” should appear on the screen, when pressed, a text or picture should appear, when pressed again, everything is welded back together

Help, I’m generally stupid how to do it

Need more info. Your query is not clear… Show us some screenshots…

Here I want it to be. There is a list of names, there are subsections in them, and when you click the subsection, the text would open

You can achieve it by using dynamic component extension
