zenPhoto 1.6.8 with zpBootstrap theme fork added (MAMP 6.9 on MAC mini) PHP 8.2.0
I am not aware of a user guide for menu or page but their usage seems obvious BUT
There is a funny interaction between menu and page
1. copy all files from zp1.6.8 download to directory
2. add downloaded zpBootstrap fork to themes directory
3. create empty db with phpMyAdmin
4. run setup and enable page
>>> basic gallery page with Search option shown [no menus]
6. Themes tab > zpBootstrap - activate [All themes (except zpBootstrap) show as deprecated so I am happy to have zpBootstrap which I use for my website anyways]
>>>Home Gallery and Search icon shown as menu items
7. enable menu_manager and zenpage plugins
>>> no change to webpage
5. enable Options > Theme > Use custom menu
>>> Home News Gallery and Search icon shown as menu items
6. Menu tab - these items are pre-populated there and set to active
7. Hide News and it gets hidden
8. create a page (not published)
>>> no change - page not displayed
9. publish it (not added to Menu)
>> page title is displayed in menu
10. Menu tab > Add Menu Items > Zenpage page select the created page and Apply
>> page title is displayed twice in menu
11. Page > unpublish the page
>> it does not appear in the menu at all
12. Page > publish and it appears twice again in the menu
13. Menu > hide the page and it appears once in the menu
I assume if menu_manager plugin is enabled and custom menu is enabled in theme then only those things not hidden in menu should be shown.
Maybe I missed some other option - I will continue checking
