How do I automatically post labelled posts to a page on blogger?

I am very frustrated right now. I have been trying to do this for weeks. I have seen that when I go on other people’s blogs some have pages on top of their blog where you can click and see the newest labelled with the name of the page. Does that make sense?
So for example I post a nail of the week post and I have a page called Nails; how do I make the newest post of nail of the week appear in my Nails page? I want to do this so that its convenient for my readers to find what they are looking for instead of them wandering around the whole blog just looking for one thing.
