I've fixed the behavioural issues on this now.

Then around the Various Inputs, do you mean the behaviour of the dropdown? As that should be covered by #16 or do you mean the icon? Either way they should be addressed in another PR to try and not conflate the two.

Agreed.

The idea was to add the "Search" input in the Various Inputs scenario.
There is no input with this style and behaviour there (label and x icon).
