Add dropdown links to new pages through the editor CMS

I have created a collection of pages, I have linked each of these to the links in the dropdown list, this is located in the navbar of my site.

Going forward I want the client to be able to add their own pages to the collection, and for these to automatically appear in the dropdown list I have built and styled for them in the navbar.

Is this possible? Or do i have to add a link to the dropdown through the designer, each time my client adds a new page to their collection?
