In the file
menu.xml located in
MyNamespace\Mymodule\etc\adminhtml\menu.xml, I understand that this file allows me to add new items to the navigation menu in admin panel.
<add> tags, there is an
action attribute that contains values that look like
something/somethingelse. For eg:
<add id="MyNamespace_MyModule::mymodule_testing" title="Some title" module="MyNamespace_MyModule" sortOrder="10" action="Part_A/Part_B" />
What should be entered in the
Part_B of the
action attribute? I doubt they are arbitrary. What do they refer to and what do they stand for? What effects would it have if I put in a wrong thing into this attribute?
