Struct DropdownItem 

pub struct DropdownItem { /* private fields */ }

One selectable option (M3EDropdownItem).

The reference’s item carries its own selected flag and the controller mutates it through copyWith. This port does not: selection is the app’s, handed down through DropdownView::selected/ DropdownFieldView::selected and requested back through on_change, per this catalog’s controlled-component rule. disabled stays on the item, since it is a property of the option rather than of the selection.

value is the identity a selection is expressed in and must be unique across an item list; label is what the field and the panel display and what the filter matches against.

Implementations

impl DropdownItem

pub fn disabled(self, disabled: bool) -> Self

pub fn label(&self) -> &str

The displayed text.

pub fn value(&self) -> &str

The identity a selection is expressed in.

pub fn is_disabled(&self) -> bool

Whether this option refuses selection.
