Remove Duplicates: Repeater Dropdown with Keyboard Navigation

Hey @yisrael-wix , I really appreciated your example on Repeater Dropdown with Keyboard Navigation. I followed it and am very happy with the functionality. Here’s my question though: the dataset displayed in my repeater is one that users are constantly adding to. Sometimes, they enter a new value that should become an option for future members (in this case, Academic Institutions), but many members have input the same value in the field I am displaying in the repeater. How can I prevent duplicates from showing up as options when a new member starts typing? I’ve tried .distinct() and a few other things from this forum, but haven’t been able to figure it out. Thanks very much!
