Hello,
I'm really new in power apps, And I need a help to walk me throu the proces of creating an app. Many thanks for You all support ! I'm trying to create an app that I could connect to lists and navigate. Im thinking about a simple layout like below. But Im trying to figure out how to add Fixed lists to items depending on the section displayed.
Example below. When I am in the "Buy" section and edit an item from this section, apart from the description of the items from the list, I also see a permanent list of tasks from this section to which I can assign a person and add informations.
So if I change the section to "Sell" it will show items from "Sell" and each items will have a checklist (fixed list) with quests "Sell" not "Buy".

How to start, what to do first and whether such a solution is possible to create .Thanks in advance for your help, I'm sure any information will come in handy. Thank you very much.
