Lightbox group

Hi,

Thanks for contacting us here about this extension.

How to create the same effect?

After clicking the thumbnail, I need to enable other pictures in the Lightbox

Sorry, this feature is not implemented yet in our plugin.
We have the tag filtering feature on the Gallery addon.

You can take a look at our demo here:

Hope it helps!
Cheers,

There is no option in the demo that I need.
