Extension with multiple screens

Opencart 3.x insists placing the controller file of my extension under extension/module folder if I want to allow it to be installed using built-in extension installer. This is ok if my extension has only one controller file. The extension I am developing has one module settings screen and several other screens and hence has several controller files. I can place the controller for module settings under extension/module folder. The question is where will I place other controller files so that the extension can be still installed using extension installer.

1. If I l keep others also under extension/module folder, each screen will appear as an entry in module list which will be confusing to the user. These screen should appear as menu options only. ( I have OCMOD to add menu items to column_left.php)
2. I can't create one folder under controller and place them in this because extension installer would fail with error - 'directory is not allowed to be written'

How do you developers manage this? What does opencart recommend?

This topic has now been moved to the OpenCart 3.0 Support > General Support section of the forum.

Why do you need multiple installations? Keep the module with settings and do everything in its install() function. No need to complicate things.
