How to lock navigation so it doesn't shift

Site URL: https://www.srees.uk/

Is there any way to lock the navigation so the navigation options i.e. staff, community facilities etc do not shift onto another line when the page is open on screens of different sizes? 

Thanks.

Just set on the flexbox nowrap

nav.header-nav-list {
    flex-wrap: nowrap;
}

 

Amazing! Thanks
