[beadegiacomo]

Hello, i'm new, and i'm sorry if this question may be already asked or maybe it's obvious. But i am creating a new project, and i wanted to add lightbox. I thought i have to add it from the gridder (like for example the carousel) but i cannot see it. What am i doign wrong?
Thank you in advance!!!

Dear @beadegiacomo
you need to activate the lightbox in the LayOptions.
Then each image on the page is a part of the lightbox automatically.
Best!
