Accordion + horizontal scroll issue

[Clou]

Hi! i cant figure out why, when the accordion is opened (marketing heading click), the horizontal scroll (orange cards) are pushed down out of the middle of the screen, but when its not opened the position is correct.

That's because you're fundamentally changing the layout/positioning of everything by opening/closing that accordion. Remember that ScrollTrigger pre-calculates the start/end positions for all ScrollTriggers so that it's extremely performant while scrolling. So for example, let's say that trigger for the horizontal section is calculated to start at a scroll position of 500...but then you open the accordion which PUSHES everything down by 100px. Well now that start position should be adjusted to be 600 instead of 500. 

 

All you need to do is force ScrollTrigger to refresh all of its calculations by putting ScrollTrigger.refresh() in your onComplete:
