Hi @gavinleung ,
Based on the needs that you mentioned, I think the Gallery control could achieve your needs.
On your side, you could consider add a Gallery control within a PowerApps app, set the Items proeprty to following:
["None", "Daily", "Weekly", "Monthly", "Yearly"]
then within your Gallery, add a Check icon, set the Visible property of the Check icon to following:
If(ThisItem.IsSelected, true, false)
Afte that, you could consider add two Dropdown controls/ComboBox controls within your app to act as Interval picker and Until picker. You could consider control the Display content within the Dropdown controls/ComboBox controls based on the selected item in above Gallery (using If function).
Best regards,
