To create a video in your featured content slider, follow the instructions below:
Create a new feature Page > Featured content sliders
In the "Page to feature" field, add the slug of a page that has a Youtube URL in the content of the page
Note the slug of the page that has a Youtube URL must contain the word "video" (e.g. video_1).
See the screenshot below as an example. Note the page with slug video_1 has a youtube video url pasted into its content section.
