Widget to display child pages from parent

Hey,

i´ve tried different things but i can´t figure out to get it work. Search doesnt show me any solution.

I want to display child pages from parent. So i´ve this structure

-Travel
–Europe
—Spain
—-Mallorca
—-Lanzarote
—- etc.
—Germany
—-Bayern
—-Berlin
—-etc.
—etc..

I want the Page “Travel” to display “Europe”, “etc”
The Page “Europe” -> “Mallorca”, “Lanzarote”, etc
And so on…

Tried it with different widgegts post loop from page but if i say under “post in” Europe it will add the id from Page Europe but it does not show the childs Spain, Germany. It just displays the page Europe itself.

What can i do to display it correctly?

Thx for your help and sorry for my bad english. Hope you understand what i want :-)
