Windows right click context menu items number limi

Question

I follow this link from Microsoft to create Windows 10 context menu.

How to Create Cascading Menus with the SubCommands Registry Entry: https://docs.microsoft.com/en-us/windows/desktop/shell/how-to--create-cascading-menus-with-the-subcommands-registry-entry

However, I found if items in the context menu are more than a certain number. Windows only show part of the context menu items.

If I have a structure like this, it will end up showing the submenu1 and submenu2. If you have even more items for each submenu, it will only show submenu1.

My Context Menu

• Submenu1

  • Items1

  • Items2

  • Items3

  • ...

• Submenu2

  • Items1

  • Items2

  • Items3

  • ...

• Submenu3

  • Items1

  • Items2

  • Items3

  • ...
