问题
I need an autocomplete with a dropdown with results categorised like in HTML select - optgroup with keyboard navigation.
I tried to implement a wicket Select component with groups based on this: Separator in a Wicket DropDownChoice with a textfield for search, but can't jump to select with "Arrow down".
Any other ideas?

I think you best option is Select2 (example: https://select2.github.io/examples.html#themes-templating-responsive-design) and its Wicket integration: https://github.com/wicketstuff/core/tree/master/select2-parent
