Please how do I implement this type ahead from an api to display the list of countries in an input field on keypress.
Here is an implementation using ng-bootstrap on stackblitz: https://ng-bootstrap.github.io/stackblitzes/typeahead/prevent-manual-entry/stackblitz.html
But I want it in angular material. Please help.
