How to group images on multi galleries with FANCYBOX?

Question

How to group galleries to show only photos from same group?

Right now getting images via data-fancybox the problem is that i have dynamical id of group.

fancybox version: v3.5.7

<a class="fancyfunc" data-fancybox-group="group_<?=$r['reference_id'];?>"  href="<?=$img['image'];?>"  data-fancybox="images">
   <img class="none" src="<?=$img['image'];?>" />
</a>

$('[data-fancybox="images"]').fancybox({

    margin : [44,0,22,0],
    thumbs : {
        autoStart : true,
        axis      : 'x'
    }
})

Answer 1

See docs - https://fancyapps.com/fancybox/3/docs/#usage -

[..] use the same attribute data-fancybox value for each of them to create a gallery.

So, replace

data-fancybox-group="group_<?=$r['reference_id'];?>"

with

data-fancybox="group_<?=$r['reference_id'];?>"
