There is no short way (To set or manage for you and especially for the clients/editors). Not matter what solution you choose their is no “multi-file-field” (So also by custom code gallery its hard to manage).
For now try this (In my opnion all solutions are “bad”):
- New tutorial: CMS Galleries made easy - #6 by chippwalters
- https://webflow.com/website/001-CMS-Gallery\
-
Full CMS Lightbox! (Top forum topic about this issue - 136 comments
- like i said “no short way”)
I hope webflow will add this feature soon (Since jan 2017 ==>Top wishlist topic by votes).
