Hi Kim & Vita,
I’m Yanay and I work for the Editor X Product team. Thank you for reaching out.
I’m not sure if this is the issue, but in general Stack is a Container. that means that the elements within will be stacked across breakpoints.
So if you go to lower breakpoints and take an element outside of the stack, this action will apply on ALL breakpoints.
you can change the stack layout (elements margins, width, docking, etc) per breakpoint. but the elements within the Stack container are attached to it across breakpoints.
Best regards,
Yanay
