When your user types in "user@gm", the plugin will suggest for e.g. "user@gmail.com", based on the first result from a list of predefined email domains.

Press the tab-key, or simply click on the suggestion to automatically fill in the rest of the domain. (or tap on the suggestion for mobile users.)

Technical notes:

You need a email input field.

Note: We recommend to create a CSS class to have a perfect align of the suggestion in the input.
