Issue with width when there are fewer slides than slidesPerView

[hdg135]

I've used Swiper on a blog page in order to display 'cards' for each blog entry. Each slide uses a cell with an image, header and text underneath with a link to the blog post. The blog system uses filtering which uses Swiper again in the same layout.

The filtering works fine, however if the filter returns fewer than 4 cards (slidesPerView: 4) then the cards width is automatically defined by Swiper and they shrink so they do not fill the swiper container anymore.

Is there any workaround or simple solution to this? The only idea I can think of is jQuery to disable the Swiper when there are fewer than 4 slides.
