I'd like to complete the best match in-line, either as an
autocompletion in the LineEdit itself (like in the KRunner text
field) or as a dropdown, but I guess that it's not possible with the
current API? So would the second best solution be to present a list
beneath the LineEdit? If so, which Plasma UI elements are suitable
for this?
That's how it looks btw:
