Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.Unless I'm missing an option somewhere in the configuration, there doesn't appear to be an option to limit the number of allowed values for a field. I have the requirement to allow users upload multiple files to one field in a form, but limit it to no more than 3. I can't see an option for that - I can either have the "multiple" checkbox unchecked which limits it to just 1 entry, or have "multiple" checked, in which case there doesn't seem to be a limit.
Would there be any way to add this functionality? Thanks

At some point I want to extend #multiple to support limits (ie > 1). It would required updates to the webform element UI and a new validation handler.
It is a medium amount of work and is now on the immediate roadmap.
