It's a drop-in system for simple dropdowns, but any entry types other
than checkboxes and radio buttons are not supported by the simple menu.

A complex menu can be made using the generator callback.

+- Either `values` or `generator` is required, the former for simple menues and the latter for complex ones.
+    - They are not exclusive, but `generator` takes precedence (e.g. `values` will be available but not used).
+- `generator` signature is `(dropdown, rootDescription, settingObject)` - `settingObject` being the addition to the default arguments.
+	- getters and setters are not handled using `generator`, and must be handled by the layout

 LibEditMode is a library that allows a developer to integrate their frames into the Edit Mode introduced in Dragonflight.
 
 It has feature parity with the systems Blizzard added to the Edit Mode, but limits its re-use of methods to limit taint issues.
-It depends on [LibDropDown](https://github.com/p3lim-wow/LibDropDown) to achieve this.
 
 For details on how to implement this in your own addon, please see the wiki:
