PageReference to show children only

[Bike]

Hi everyone,

I have pages each with a PageReference field.

Now I need to set up a selector for that field to show only their child pages.

It must be something like parent.id=1024 but without that fixed id. Or maybe I need a totally different selector?

Does anyone unterstands? ?

Maybe just $page->children in the custom selector field?

Thanks @Gideon So, but that's not working. That field doesn't accept variables like $page ...

Here's what I'm talking about: Show children of that page only... I don't even know, if it's possible.

Try put $page->children into the custom PHP code field.

Thanks @Gideon So, I actually managed to get it working with a hook.

Now I have another field that lists all items of a repeater field. It looks like this:

Is there a way to change the appearance of that label which is showing that mysterious numbers?
I'd like to have a simple numberation (since the repeater items have no titles).
Do I have to change the hook code to achieve that? I have no clue ....
