Printing navigation hierachy on a separate WP-page

Hello

I am fairly new to WordPress and I feel I have done an OK job trying to check this up before posting.

I have a category called Articles and several children which obviously are the articles in question.
The drop-down menu choice Articles thus generates in a very long and non-user-friendly menu.

What I want to do is to only have a non-dropping down menu choice Articles. When it is clicked it takes the user to a page where all children of Articles are listed automatically:

Articles

• Article 1
• Article 2
• Article 3

My idea is to have this list updated automatically so that I don’t have to manually enter each new article that is added as a child to Articles.

I did find some PHP code (get_post_ancestors()) but from what I figured it can not be used on the pages that you create through the WordPress editor.

My apologies if this question comes across as ignorant due to some blatantly obvious answer, but I hope some generous soul might shed some light on my issue.

best regards
-L.T.
