I have googled this page: http://forum.webflow.com/t/how-to-add-lightbox-in-cms/19659 and this is similar question. Are there any changes with this issue?
Unfortunately not. The lightbox doesn't natively support CMS items yet, and we have to resort to using a list with a limit of 1 for each slide.
Are there any assumptions when lightbox will natively support CMS?
You can create custom lightbox
thanks both of you
