I have a few questions about using the tags field.
1. Is there a way to have validation limit the max number of tags that a form will accept?
2. Is it possible to have AJAX tag suggestions as in wp admin?
3. Is there a way to add a "choose from most popular tags" as in wp admin?
Thanks!
1) Currently there is not a built in option for limiting the number of tags. If you wanted to do this you would have to write your own custom validation using the gform_validation hook.
2) AJAX tag suggestions are not currently a feature, although it is a feature we would like to add in the future.
3) Again, this could only be done via a customization. You could use a standard drop down or checkbox field to capture the data and then use the available PHP hooks to use that data as the tags for the post that is created.
