Struct Select 

pub struct Select<'a, T, F = fn(&T) -> String>
where
    F: Fn(&T) -> String,
{ /* private fields */ }

Select widget - dropdown select box.

A dropdown select component that renders as a compact closed state and opens a popup overlay with selectable options when activated.

Implementations

impl<'a, T: Display> Select<'a, T, fn(&T) -> String>

pub fn new(options: &'a [T], state: &'a SelectState) -> Self

Create a new select widget with default option rendering.

impl<'a, T, F> Select<'a, T, F>

where F: Fn(&T) -> String,

pub fn render_option<G>(self, render_fn: G) -> Select<'a, T, G>

where G: Fn(&T) -> String,

Set a custom option renderer.

pub fn placeholder(self, placeholder: &'a str) -> Self

Set the placeholder text.

pub fn label(self, label: &'a str) -> Self

Set the label (border title).

pub fn style(self, style: SelectStyle) -> Self

Set the style.

pub fn focus_id(self, id: FocusId) -> Self

Set the focus ID.

pub fn render_stateful( self, frame: &mut Frame<'_>, area: Rect, ) -> ClickRegion<SelectAction>

Render the closed select box and return click region.

This renders the compact closed state of the select box. Call render_dropdown separately when the dropdown is open.

pub fn render_dropdown( &self, frame: &mut Frame<'_>, anchor: Rect, screen: Rect, ) -> Vec<ClickRegion<SelectAction>>

Render the dropdown overlay.

Call this when state.is_open is true. Returns click regions for each option.

Arguments

• frame - The frame to render to
• anchor - The area of the closed select box (dropdown positions below this)
• screen - The full screen area (for bounds checking)

pub fn render_to_buffer( self, area: Rect, buf: &mut Buffer, ) -> ClickRegion<SelectAction>

Render the select box using Buffer (Widget-style rendering).

This is useful when you need to render without a Frame reference.
