I'm trying to create a dynamic searchable select. I need the options to be set dynamicaly as I type in the searchfield. I've accompished this on an input using autocomplete, but I need it on a select. My ajax script would return the 20 first rows matching the searchfield, limiting the number of select options while typing.

I've tried setting up a snippet to show what I'm looking for: https://mdbootstrap.com/snippets/jquery/ererling-sande-no/2112791
