Design tips for combobox (search dropdown)s

Bold or color the matched substring in each option so users can visually confirm why a result surfaced.
Keep the highlighted-row background subtle (a tint of your accent, not a solid fill) so option text stays fully legible.
Limit the visible listbox to 5–7 rows with internal scroll — a combobox that grows past the fold is harder to scan, not easier.
