Struct Dropdown

pub struct Dropdown {
    pub selected_item: Option<Element>,
    pub children: Vec<Element>,
    pub key: DiffKey,
    /* private fields */
}

Select between different items component.

Example

fn app() -> impl IntoElement {
    let values = use_hook(|| {
        vec![
            "Rust".to_string(),
            "Turbofish".to_string(),
            "Crabs".to_string(),
        ]
    });
    let mut selected_dropdown = use_state(|| 0);

    Dropdown::new()
        .selected_item(values[selected_dropdown()].to_string())
        .children_iter(values.iter().enumerate().map(|(i, val)| {
            DropdownItem::new()
                .on_press(move |_| selected_dropdown.set(i))
                .child(val.to_string())
                .into()
        }))

impl Clone for Dropdown

fn clone(&self) -> Dropdown

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for Dropdown

impl PartialEq for Dropdown

fn eq(&self, other: &Dropdown) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
