Adds the lightgallery.js with video support. To display other content in the modal box, the text element containing the link must be given the class html_modal.
The trigger for the iframe, eg. for YouTube is a[target="lightbox"]. For example, the following could be added to the be_tinyMCE.html5 in the templates directory:
target_list: [
{ title: 'same window', value: '' },
{ title: 'new window', value: '_blank' },
{ title: 'open in lightbox', value: 'lightbox' },
], This will then allow you to select “open in lightbox” in the “open link in…” field in the editor. Commercial licensing: https://sachinchoolur.github.io/lightgallery.js/docs/license.html
