Hey @jornaagaard, I just had the same problem, you probably found it already:
Did not find a solution so far, but one thing to avoid: If the Cycle2 slider sits inside a dynamic template, you may encounter further problems. Because if the slider starts inside one dynamic item, it will of course stay there if you click through the slides. And (provided you manage to assign the data-cycle-hash) that would mess up your slug like this:
site.webflow.io/collection/item1#item1 site.webflow.io/collection/item1#item2 site.webflow.io/collection/item1#item3 etc.
I'm just about to dump the slider and maybe build a custom dynamic lightbox from scratch, but I'm pretty sure that will lead to other problems... Could be so much easier if we had a dynamic slider out of the box, but I can't wait for that, deadlines and stuff...
If you find another workaround, let us know, would totally appreciate it!
