If you want to force the use of slidesToShow with centerMode, you do not need to change the core code. I did it like this :

// 1 - init
$('"#carousel").slick({
	centerMode: true,
	infinite: true,
	slidesToShow: 3,
	speed: 500,
	variableWidth: true,
	accessibility: true
});
// 2 - force slidesToScroll in centerMode
$('"#carousel").slick('slickSetOption', 'slidesToScroll', 3, true);

This works for me but please notice :

• do not use this with focusOnSelect set to true or you will have the bug describe on this thread
• a real core fix would be better and greatly appreciate

Could you please remove that check? I think if we notice something wrong when using centerMode we can just set slideToScroll=1 ourselves.

@AlexeyJersey It’s 2021. Slick died three years ago. Don’t use it.

I also had to move to another slider to support more native touch usage like momentum scrolling: https://swiperjs.com/

Nonetheless, I have a PR out there if anyone cares to 👍 it or whatever: https://github.com/kenwheeler/slick/pull/3513

Hey guys I just wanted to share that I have found a slider that has all the features that Slick has and it works great in my personal developing experience. https://flickity.metafizzy.co/ You might want to check it out, I hope you will find this helpful. Nonetheless, Slick is great, but it has some flaws (for example, you cant really slide multiple items all at one time, depends on the amount of user interaction - how much he scrolled). so Slick will go only 1 slide or 2 slides each time. it wont be dynamic.

@leggomuhgreggo For the most part it works. I have noticed that it using

   `focusOnSelect: true,`

gets out of sync.

@kenwheeler, happy to check this out and see if I can come up with a fix, love to gets your thoughts before I beat myself to death with my monitor trying to figure it out.
