title: Select with input field HTML/Angular 6
body: <p>I need to have an input field with an arrow on the right so when I press on the arrow I have the bahaviour of a select tag ( a dropdown list of options). I was wondering if it's possible to do this in HTML/Angular 6... I found the solution of a datalist but it's not actually the result I'm looking for because with this solution if I enter some value in the input, which is not present in the datalist, and then click on the arrow anything display because datalist filters what to display depending on the input value.</p>
  Hope it's clear enough.
