@bpw without knowing anything about your data, your data source, or your app, but assuming you want both the Parent Gallery and the Child Gallery to be on the same screen, and you do have a field which links both records together:
One method:
1. Create a Gallery and set the Items property to your data source which contains the parent data
2. On the OnSelect property of the Parent Gallery, enter
Set(ThisSelectedItem,ThisItem.'Your common field')
3. Create a Gallery and set the Items property to your data source which contains the child data
4. In the Items property of the Child Gallery, enter:
Filter(
'Your child data',
'Your common field' = ThisSelectedItem
)
5. Set the Default property of the Parent Gallery to:
{}
6. (Optional), set the OnVisible property of the Screen to:
Reset('Your Parent Gallery');
Set(
ThisSelectedItem,
Blank()
);
Another simpler method:
Filter(
'Your child data',
'Your common field' = 'Your Parent Gallery'.Selected.'Your common field'
)
If your data source is Dataverse, the above process is slightly different, but the same overall principle applies.
Regarding the second question, you could make the 2nd Child Gallery editable, but unless you need to update multiple records at a time, I would recommend creating a Form which is associated to the selected item in the 2nd Child Gallery.
