The tut is using substrings I mentioned above. What’s wrong with it? Do note that we know absolutely nothing about how things work on your end - not sure what your expectations are.
- ensure your actors have IDs that can be looked up - substrings could work OK
- loop through the array of scrollbox children; when matching strings are found, add those widgets to an array
- clear the scroll box, repopulate with the filtered array
That’s the gist.
