Put a page in a submenu.
There are two steps to tell the system that the page will end up in a submenu. First of all, we have to tell her what page she is going to find, that she will be called "Parent Page". To do this, go to the "General" tab. Then, choose a page in the "Page parent" field. For the example, we will choose "Hotel" as the parent page. If you do not want one page to fall below another, choose "Root". The page will be in the menu strip, and therefore visible at all times
