Combo: Performance issue with 20k options #18

Description

@sbscan

Description: When using the combo component with ~20,000 options, performance issues occur. Other UI libraries handle this scenario more efficiently. Possible improvements:

Type‑ahead filtering: Show options only after the user types 1–3 letters.

Virtual scrolling: Render only visible options instead of the entire list.

Limited options: The dropdown opens as soon as the user starts typing (from the first character),
but only shows a capped number of items (e.g. 5).

Alternative component: Provide a separate “select without typing” component for users who prefer browsing all options.
