Custom Javascript embedding not working

Im trying to embed a video gallery from an external site.

Only thing is when I embed it into a html block, nothing shows up, just empty box...

Apparently the embed code uses a custom javascript.

Does anyone know if Dolphin allows this or blocks it?

Thanks - Tim

You can always try inserting the code into the HTML block directly through the database.

how do i do that?

Database > sys_page_compose > HTML block

You need to edit this entry and add the code to the Content box. Once done, save your changes and clear your site's cache. I make no guarantee that this will work or not result in your site looking like the set of  BBC's Threads.
