Hey guys!
I need to make training videos available for a software we are developing. Our website was created using the latest Wysiwyg Web Builder.
I would like to have just one screen, where it would be divided into two blocks. On the left side, a list (links) with the videos and on the other, the videos themselves.
As this will be run practically within a window of our software, I would like the window to be fixed, so that the user cannot scroll it. However, the video list part does, as there will be several links, separated by groups (or topics) with the videos. They will not be hosted on any such website,
staying in a folder on our own hosting. Do you have an example showing how to do this?
Any help is welcome!
Thank you very much!
