Nav Bar Menu drop down lists

Is there a way in coding to create events from the click of a text item in the standard drop down menu?

When I open the developer tab I can’t access the drop down menu so I don’t know how to add events as I do with other items such as images, buttons etc.

Thanks for any help.

While waiting for response I’ve tried to create my own menu myself using container boxes and buttons. Each main menu item having a container box below which is hidden until the user rolls over the main menu item and then the container box hides again when they roll off - however, the mouseon and mouseoff sometimes work and sometimes don’t! If this is the way I need to go, can anyone help me to be able to create my own menu that functions properly and I can create events for in velo. Many thanks
