Autocomplete - Add option to show all values

[dchatzinaki]

In the autocomplete component we need to provide the ability to show all the values when the user clicks the input. We'll create an extra optional attribute called showAllValues by default set to false and the user can change to true. This is similar to a default dropdown, so the autocomplete is rendered with a dropdown arrow to convey this behaviour.

showAllValues?: boolean

For a working example please refer to the following component and demo
