What to change
Ask your supplier to keep every option reachable and the chosen value clear, including larger text and any search keyboard used inside the list.
A worked example
Illustrative example
A visitor opens a long location list, reaches an entry near its end and returns to the form with the complete selected location visible.
Why this matters to your practice
Long choice lists need to remain manageable on a small screen. A visitor selecting a branch should be able to reach the final entry, recognise the chosen value and close the list deliberately. Ask your supplier to demonstrate the longest real set of options with larger text. A custom-designed selector carries extra interaction responsibilities, so its appearance alone should not justify replacing a dependable standard control. If search is included, check that the keyboard does not hide the remaining choices or dismissal action.
A practical review example
A location selector may contain enough entries to extend beyond the phone screen. Ask the supplier to reach an option near the end, select it and reopen the list. The current choice should be identifiable and dismissal still available. Watch whether the list or the page behind it scrolls. If search is offered, open the keyboard and repeat. A custom design should earn its place by supporting this complete interaction, rather than replacing a dependable standard selector solely for appearance.
How to check the result
Accept when every option can be reached, selected and verified without unintended background scrolling or a trapped full-screen panel.
A mistake to avoid
Replacing a dependable native selector with a custom panel creates additional interaction behaviour that must be tested explicitly.
