Checks that the input is a valid website URL format.
Offers validation presets: Full Name (splits the input into first and last name, with a minimum character length you can set for each), Alphanumeric, Letters Only, and Numbers Only. You can also set a minimum and maximum character length without a preset.
Set a minimum and/or maximum value. Submissions outside the range are rejected.
Set a minimum and/or maximum character length.
Set a minimum and/or maximum number of selections. Useful when you want the visitor to pick at least two options, or to cap the selections at a specific number. Add a custom error message to explain the requirement clearly.
