Support for slide groups/ downward slides?

[zeigerpuppy]

I have been preparing a conference talk with manim-slides. It's a great tool!
I was wondering if there is any support for vertical slide groups in manim-slides?
These are implemented in reveal.js, but I can't see a method for making one of these slide types with manim-slides.

Hi, thanks for your feedback! No, there is (currently) no support for such feature. I think we could implement this by adding metadata to slides (using extra keyword arguments with next_slides, and use that metadata inside the RevealJS template to choose between vertical and horizontal slides). I have never used vertical slides myself (because I prefer to have one continuous presentation, one timeline), so I never invested much time on this question.

Thanks, I can take a look at this when next using manim-slides. a keyword sounds like a good solution.

The main benefit I find of the vertical "groups" is when navigating back through slides from the overview (esc) menu, usually when someone asks a question at end of a talk.

For instance, a presentation may be made up of 20 slides (let's say 5 each in Intro, Assumptions, Calculations, Conclusions).

• Navigating back to slide Assumptions:2 would take 14 slide moves with horizontal only slides, but only 3 slide moves with vertical groups...
• and I also find it easier to remember because the vertical groups can be easily arranged by theme/subject

That makes sense! Looking back at https://revealjs.com/vertical-slides/, maybe a simpler solution could be to have all slides in vertical mode by default, and have a special keyword in next_slide that triggers a new horizontal mode. To provide the same behavior as previously, we could check afterward if the presentation only has one horizontal slide and, if that's the case, unravel all vertical slides into horizontal ones.

FYI, I created #570 to better document a request for this new feature :-)

great, I will update/comment there
