Feature request: Maintain active item index when not closing on select

[skimbels]

When selecting an item and the select is configured to remain open on selection, it would be great if the next option in the list is selected rather than the first element each time.

This is especially apparent when navigating using the keyboard.

I have tried maintaining the activeIndex property in the select callback but this only partially works. The last used index is preserved for navigation purposes, but the first item is marked as active.

Seems like a valid request feel free to submit a PR 😃
