Version

v4.1.4

Description

I have multiple, working slides on a page.

What I'm trying to achieve is allowing slides to loop and autoplay when there are enough slides to do so.

According to the docs, something like this should probably work, as I'm able to control other options based on isOveflow:

slides.on('overflow', function(isOverflow) {
  slides.go(0);
  slides.options = {
    clones: isOverflow ? undefined : 0,
    autoplay: true,
  }
});

The clones option is working as expected, and if I put another option in there like gap and amend it based on isOverFlow then it works fine, even with a single value, proving that the function is working as expected.

I don't know why autoplay isn't controllable in here, as it seems I'm needing to enable it in the main options list, which means that when there are not enough slides to fill the track, it still autoplays, even though the clones are not present.

Other relevant options:

  type: 'loop',
  gap: '1.5rem',
  pagination: false,
  autoWidth: true,
  arrows: false,
  interval: 4000,
  speed: 4000,
  perMove: 1,
  easing: 'linear',

Steps to Reproduce

1. Create carousel with enough slides to overflow, then another that does not
2. Implement the on overflow function and try to control autoplay only when overflow is true

Expected Behaviour

Slides should only autoplay when there are enough to overflow. Currently it does not seem like we can trigger autoplay based on overflow.

I did see #1362 however thought this was a different issue.

It might be that the cause includes the addition of autoWidth too, however it seems that the above combination of options means autoplay does not work as expected. It's either on or off for both tests.

Aha! Ok, so when you have a set number of slides via the perPage option, rather than using autoWidth it works as expected.

By this I mean that with autoplay enabled, only the track that is overflowing actually plays, whereas the other does not.

In which case, is there a way of using autoWidth (as the images on my slideshow are different sizes) alongside autoplay, but only when the track is overflowing? I still believe this should be able to be forced via the isOverflow as mentioned above.
