For long lists, the dropdown components in our create deployment dialogs are not very usable. See screenshot
- List does not appear to be ordered in a logical way
- List extends below and above screen
- List covers the text input area, so even though you can filter by typing, you can't actually see what you're typing
Things to consider: max height of dropdown, display it only below, only show x number of entries at once, maybe offer a choice to sort by name or by most recent. Most recent makes most sense for releases, alphabetical makes most sense for device groups.
