Hi,
in this page: http://davidroda.com/courses/videos-whiteboard-con-videoscribe/ the sidebar no is sticky but in the rest of the web yes.
I have spoken with the support of learndash (course creation plugin that generate the cpt) and They have told me to ask you if Generatepress settings can apply to custom post types.
All I want to do is convert the leftsidebar of this page as sticky (as the rest of the web).
I do not know much about the programming but yes you say to me that code I have to put and where I will without problem 😉
Thanks and regards!
