Telephone Input

This extension for WYSIWYG Web Builder adds an international telephone number input field with country flags, dial codes, formatting, validation, and optional hidden output of the full international phone number.

It is based on the intl-tel-input library: https://github.com/jackocnr/intl-tel-input
Visitors can select their country from a dropdown list, type a phone number, and optionally receive validation feedback when the number is invalid.
