Display ALL pages of a specific level

Hi,

I already know that there is a possibility to create a page collection based on the siblings (all pages of the same level excluding the page itself).

but is there a possibility to create a collection with ALL pages of a specific level? i mean, self + siblings?

You can just get the parent, then get the children of that parent.

{% for child in page.parent.children %}
...

mhkay thx :)

should really spend some time learning twig :)
