Navigate without opening a new window

I’m sure this is a really stupid and simple question, please bear with me, I’m a total begginer at both Ionic and Angular :smile:

I have a link in one of my pages that’s supposed to navigate to another page, I did this via this.navCtrl.push(OtherPage);
However, when the link is clicked, the app opens the page in a new “window” and the menu button is replaced with a back button that takes you back to the previous page (the one with the link).
I can’t for the life of me figure out how to open the new page “in” the previous page instead of “on top” of it and the docs aren’t really helping. What’s the correct way to do this?

Did you read the ones for setRoot()?
