As an eg: I want to display all the related lists i.e all the child object records for an account object, i would be displaying the account records in the form of a table and there would be a button to show a pop up of all the related lists as tabs and also if possible edit those records
On your account page, create a row action that shows a popup. Next, add a page include component and put the accountId as a URL parameter. Page Include tutorial https://docs.skuid.com/latest/en/skuid/components/page-include/index.html
Next, create a new page that has all the related list models and tables in a tab set.
For each model, create a condition that is filterable based on URL parameter for the account Id.
Additionally, you can add render conditions to each table to hide or display as needed.
On this new page, you can set tables to be editable as needed.
