Does apple notes in the macos and ios environment have the ability to create subordinate points?
Mac mini, macOS 11.5
Yes, but its simplicity makes me wonder what you've tried and what happened or I have no idea what you mean.
If you look at the this text editor on the discussion there is a hamburger with a right arrow. I don't see that option in Apple Notes. Indenting is used in numbered lists to create the a) on 1 to make 1(a) (b) (c) etc. Or subordinate bullets etc.
In macOS, just use the tab (shift-tab) to indent.
You can also use cmd-] (cmd-[) as shown in the Format menu > Indentation.
In iOS, if you click on the format button (Aa) icon, there are indent buttons.
