I am creating StaffPage following Tutorial-2 (but with much more fields than there)
I want the behavior similar to one in "Create Page"

"Page name" entered fills also "Navigation label" (which one can override)

I want "Last name" and "First name" entered fill "Page name"= "Last_name First_name" which one can however override

I understand that this should be done through javascript. Thank you in advance
