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

jrockowitz commentedRight now, #multiple only support TRUE (1) = UNLIMITED VALUES or FALSE (0) => ONE VALUE.
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.
