This module only displays an external iframe once the user has clicked on a button (2-click solution). This can be used, for example, to comply with data protection guidelines.
This could be a Facebook Like Box, a Facebook Comment Box, a YouTube video, Google Map or whatever. In accordance with the GDPR, it could be mandatory to let the user decide whether or not to load the contents of an iFrame.
In this module, you can enter an iFrame link and have it loaded as soon as the user gives consent by clicking on it.
