Function leptos::Show

pub fn Show<W>(props: ShowProps<W>) -> impl IntoView
where
    W: Fn() -> bool + 'static,

A component that will show its children when the when condition is true, and show the fallback when it is false, without rerendering every time the condition changes.

The fallback prop is optional and defaults to rendering nothing.

let (value, set_value) = create_signal(0);

view! {
  <Show
    when=move || value.get() < 5
    fallback=|| view! {  "Big number!" }
  >
    "Small number!"
  </Show>
}

Required Props

• children: ChildrenFn
  • The children will be shown whenever the condition in the when closure returns true.
• when: [W]
  • A closure that returns a bool that determines whether this thing runs

Optional Props

• fallback: impl Into<ViewFn>
  • A closure that returns what gets rendered if the when statement is false. By default this is the empty view.
