I have both "Meta Box Group" and "Meta Box Conditional Logic" installed, they both work as they should.

But what I now want is make fields appear based on the group 'count', so if a cetain group contains more than 3 items, make field X appear.

So for example
```
'visible' => array(
  'when' => array(
     array( 'meta_box_group', '>', 2 ),
   ),
)
```
Is something like that achievable in any way?

Thanks in advance!

Hi Pascal,

Did you mean by number of clones? If that, there's no built-in rule to do that. You might want to trigger your own JavaScript action at after_clone hook:

Hi Anh,

Thanks for your suggestion! I was also thinking about a custom callback like explained in the documentation.

Now I wonder if something like this could work?
```
'visible' => array( 'get_clone_count()', '>', 2 )

function get_clone_count(){
  $x = some way to get the 'meta_box_group' clone count
  return $x;
}
```
But then I how do I get data of that from inside that function?
