Struct Select 

pub struct Select<T: Clone + PartialEq + Send + Sync + 'static> { /* private fields */ }

A select field for choosing one option from a list.

Implementations

impl<T: Clone + PartialEq + Send + Sync + Default + 'static> Select<T>

pub fn new() -> Self

Creates a new select field.

pub fn key(self, key: impl Into<String>) -> Self

Sets the field key.

pub fn options(self, options: Vec<SelectOption<T>>) -> Self

Sets the options.

pub fn title(self, title: impl Into<String>) -> Self

Sets the title.

pub fn description(self, description: impl Into<String>) -> Self

Sets the description.

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

Sets whether options display inline.

pub fn validate(self, validate: fn(&T) -> Option<String>) -> Self

Sets the validation function.

pub fn height_options(self, height: usize) -> Self

Sets the visible height (number of options shown).

pub fn filterable(self, enabled: bool) -> Self

Enables or disables type-to-filter support.

When filtering is enabled, typing characters will filter the visible options. Navigation keys (j/k/g/G) still work for movement. Press Escape to clear the filter, Backspace to delete the last character.

pub fn get_selected_value(&self) -> Option<&T>

Gets the currently selected value.

pub fn id(&self) -> usize

Returns the field ID.
