Replace or hide tabs

Ionic Framework ionic-v3
1

I started a tabs project which has default 3 tabs, I need help in couple of things.

1. How can I hide tabs properly on specific pages? I have tried this approach which works but not sure if its the correct way, so when I go to somePage I have this implementation

constructor(){
…
this.tabBarElement = document.querySelector(’.tabbar.show-tabbar’);
…
}

ionViewWillEnter() {
this.tabBarElement.style.display = ‘none’;
}

ionViewWillLeave() {
this.tabBarElement.style.display = ‘flex’;
}

2. If I have tabs #HomePage, #AboutPage, #ContactPage at home page, when user click on #ContactPage tab I would like to replace #AboutPage and #ContactPage tabs with #ProfilePage and #DetailsPage tabs, and when user click on #HomePage it should display default tabs again.

Thanks for any help.
