Question regarding thumbnail navigation. Is there away to have a scroll for the thumbnails if there are a lot of photos in the slideshow? Right now if I put more than 10 in the thumbnail area the thumbnails go to another row.
This is a CSS issue. You can set the element that contains the thumbnails to overflow in a horizontal way and induce a scrollbar.
Touch tip: use -webkit-overflow-scrolling: touch;
However, I don't see any thumbnail options in the docs.
Here is an example of the CSS on CodePen.
