Can someone tell me how to completely remove the lightbox and the fly-out edit and delete keys?
Hello,
The lightbox contains 3 default buttons (‘Save’, ‘Cancel’, ‘Delete’) that are specified by the buttons_left and buttons_right configuration options.
So, to remove some of them, you just need to update these configurations in the next way.
If you added custom button (edit), you shoud remove it from your code.
Also you can set read-only mode for events or whole Scheduler, if you need to forbid editing.
Please, check the article:
