Iframe Lightboxes

[Johani]

This is a desktop-only theme component that adds the ability to open iframes in lighboxes

This component adds an “expand” button on top of iframes you enable it on:

Clicking the button will open the iframe in fullscreen in a lightbox:

Clicking either the dark area around the iframe or the x at the top right corner closes the lightbox. The same way it works for default image lightboxes.

Settings

You target the iframes based on their origin domains in the component’s settings:

Whatever domains you specify here also need to be whitelisted in the allowed_iframes setting to show up in posts in the first place.

You target the iframes based on their origin domains in the component’s settings:

I suppose these iframes still also need to be activated in the allowed iframes site setting?

[Johani]

Correct, this component will not mess with any whitelisting settings at all.

In order for any iframe to show up in the cooked content of a post - expandable or not - it has to be on the list of allowed_iframes setting like you pointed out.

I’ll add a note about this to the topic.
