Using a CMS collection template and a collection list, using the built in filter to only select CMS items (excluding the current one) into a collection list that is running swiper.js - this breaks the swiper carousel.
The only thing I can think off is the swiper.js is being initalized before the filtering.
Is there are callback when the filtering is complete?
I’m assuming you’re referring to Webflow’s filtering? That occurs server side. The collection list HTML only renders the items defined by your filter.
Check to make sure you have enough items- if you’re doing e.g. looping with Swiper, there’s an overlap, so depending on the overlap size you set you need a certain minimum number of items for it to function properly.
If you’re talking about something dynamic like Finsweet List Filter, that’s a different story entirely.
