I have a reporting tool where input filter has standard date from, date to, some checkboxes, but main input is a list of comma separated items (~1000).
Now I don't want to make a huge textblock that would contain them all, because it would look ugly in comparison with other small fields. Also even if I showed them all, I doubt that user would be able to easily locate a specific entry.
My idea would be for a small text field. When clicked I would show extended popup where user could see his whole input, but after closing, the text field would show first X items and redact the others with ellipsis (perhaps it could say "… and Y more").
Is there a better way?
