I have a few custom fields tied to request form questions that have hundreds of options. I've given feedback earlier this year, to help with the unwieldiness of managing a form on the back end with that many single select options.
Today is for UX. It would be great if you could search in the selection field, much in the way any form on the internet allows you to type, say "Ho" to jump to "Horse" as a selection. This way, people filling out the form aren't endlessly scrolling.
