Hello,

I can not well that I want to restrict the characters available in Textarea.

For example, but I want to use only lowercase characters, digits, and hyphens, how do I write.

Currently, my setting of a Textarea on Validations tab is below.

"Required" is "Yes"
"Regex Syntax" is "([a-z0-9-]+)"
"Validation Rule" is "Regex"

In this setting, the characters such as '=' and '@' is get through.

Is there any good idea?

Thanks,
