Regex

Options include a field for inputting a custom regex and the message (alert) to display on fail. Once installed, it will appear under the Required/Validation column in Admin and Site views with #3 selected (Form & Content Types) and under Required/Validation in Search Form view with #6 selected (List & Search Types).

IMPORTANT. If you encounter JavaScript issues with live plugins, in the settings winder for the plugin, click “reset”. Then return to configure the plugin.
