Builds Cascader

The code that drew it

A still frame holds a repeating animation at its first frame and a one-shot at its last, because a still of a moving thing is not reproducible. Run the gallery to review motion.

fn cascader(window: &mut Window, cx: &mut App) -> AnyElement {
    if !cx.has_global::<SceneCascader>() {
        let cascader = cx.new(|cx| {
            Cascader::new("scene.cascader", window, cx)
                .name("Fixture destination")
                .selected("release-notes")
                .options([
                    CascaderOption::new("guides", "Guides").children([
                        CascaderOption::new("getting-started", "Getting started"),
                        CascaderOption::new("configuration", "Configuration"),
                    ]),
