I'm trying to figure out how to create a drop-down list inside of panel, that has buttons in it, like you see in the image for "Mirror". At the moment, I've already figured out how to add a custom button to this panel with the code bpy.types.VIEW3D_MT_object_context_menu.append(), but now I just need to know how to create a drop-down list.

enter image description here

You are interested in bpy.types.Menu. Docs: https://docs.blender.org/api/current/bpy.types.Menu.html#bpy.types.Menu

Here is the example of a code needed to create nested menu you have shown:

import bpy

class MT_NestedMenu(bpy.types.Menu):
    bl_idname = "nested.menu"
    bl_label = "Nested Menu"

    # Drawing a nested menu with three operators(buttons)
    def draw(self, context):
        layout = self.layout
        layout.operator('object.some_operator1', text='Button1')
        layout.operator('object.some_operator2', text='Button2')
        layout.operator('object.some_operator3', text='Button3')

# Defining function to append NestedMenu class to the Object Context Menu
def add_to_view3d_mt_object_context_menu(self, context):
    layout = self.layout
    layout.menu('nested.menu', text='Menu')

# Registering/Unregistering
def register():

def unregister():

if __name__ == "__main__":

Hope it helps!
