For anybody else who may be stuck or having difficulty with this, ignore the ‘autocomplete=”no”‘ value, and don’t use ‘display: block’ to show the ‘.pac-container’.
go into your chrome devtools and make sure you can see the .pac-container div. set the z-index of that div in your css. When there is a searched value, google will change the display to block and handle the showing and hiding, you just have to worry about the z-index.
