Type the first character of topics from http://uxofvr.com to see the auto-complete.
(a-z, 2,3). Use ESC to hide the dropdown.

Uses a variable to capture the content of the search field then uses the javascript method
"{search}".charAt(0) to capture the first character of the search string to then change the container state property of the auto-complete dropdown to match the first character typed.
