Struct SubmenuBuilder 

pub struct SubmenuBuilder<'a> { /* private fields */ }

Builder for creating dropdown submenus with consistent styling.

This builder provides a fluent API for constructing submenus with icons, text items, separators, and toggles. show draws the rows into the Ui it was created with; the drawing toolbar calls it inside its flyout.
