Yeah to set the block display to none somehow works. But that's not really what I wanted to do.
I have 6 slides at mobile viewport and 2 slides at desktop viewport
wanted to distribute the content of 6 mobile slides into 2 slides at desktop viewport.
The work around for now is to have 4 empty slides at end of desktop viewport and set display none,
But I don't think that's not really practical .
These kind of issue has different solution , and the solution is two have two separate slides and use mobile and desktop redirect method I guess, because yes we can manipulate the CSS at different viewport but there is no way to control HTML elements and content written in HTML document.
I didn't understand the last paragraph in your post.
So, can't you just make two slides visible at the desktop breakpoint and the other six invisible using Display - None.
Then at the mobile breakpoint make the six slides visible and set the other two invisible using Display - None.
Will that not work for you?
The problem now is that you will have to wait for CoffeeCup to answer to my last post as to whether or not this can be done to entire slides and not just to a(n) element(s) in a slide. And, you will have to wait for the next version of the RCS software to fix the general problem of Display - None causing slideshows to freeze up.
