Validator on field that has to be updated although it already has content

[Tiago Pereira]

I want to add an field validator that makes sure that users fill in the 5 why's & answers's on root cause of the finding field, the issue is that regular validator will not work as field has already some content

Hi Will,

There is a Custom Field type "Label", you can use that Custom Field type and you will be able to have a field that works like the existing Label System Field.

Thanks for replying Mogavenasan.

Is there a way to limit this field so users can only select one label?

Heya Will,

Unfortunately, I don't think you can do that with that custom field type. However, custom field allows you to inject Javascript under the field's description section, something like this KB. With this, perhaps you can inject a Javascript that limits the field to accept one value.
