        builder.item("Copy");
        builder.item("Paste");

}

Implementations

impl DropdownMenu

pub fn new(id: impl Into<Id>) -> Self

Create a new dropdown menu

pub const fn open(self, is_open: bool) -> Self

Set the menu to be open (used internally for submenus).

pub const fn position(self, position: PopoverPosition) -> Self

Set the menu position

pub const fn width(self, width: f32) -> Self

Set the menu width

pub const fn item_height(self, height: f32) -> Self

Set the height of each menu item row

pub fn show_ui( self, ui: &mut Ui, trigger: impl FnOnce(&mut Ui) -> Response, content: impl FnOnce(&mut MenuBuilder), ) -> DropdownMenuResponse

Show with inline trigger widget. Open/close state managed automatically.

The trigger closure renders the trigger widget (e.g. a button). Clicking it toggles the menu open/closed. The menu auto-closes on selection or click-outside.

pub fn show_at( self, ctx: &Context, anchor_rect: Rect, is_open: bool, content: impl FnOnce(&mut MenuBuilder), ) -> DropdownMenuResponse

Show the menu at a specific anchor rect with explicit open state.

Use this for context menus where there is no trigger widget — the caller controls when the menu is open (e.g. on right-click).

pub fn show( &mut self, ctx: &Context, anchor_rect: Rect, content: impl FnOnce(&mut MenuBuilder), ) -> DropdownMenuResponse

Show the menu anchored to a rect (internal, used by submenus and show_ui).

Trait Implementations

impl Clone for DropdownMenu

fn clone(&self) -> DropdownMenu

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
