CMS Video HLS and YouTube HTML Load Test

We want to create a CMS that can manage user profiles, videos, images, social media information and create dynamic carousels. All together it’s pretty complex but induvial its simple parts. What we want is to build the key parts to test them separately, then assemble the whole thing. Please have a look at the attached file. We want to be able to load Live HLS streams and YouTube playlist without reloading the entire page. We want the user to select/trigger a stream to load. Currently, this data sits between two divs, the HTML data gets selected from the database and loads; and if the database is unreachable load a default value. Nothing complex, please. The next job after this will be to create a dynamic image carousel from a database, super simple stuff, and have it include a specified HTML social media feed. Have a look and let me know.
