# Collapse

```rust demo
use std::collections::HashSet;

let value = create_rw_signal(HashSet::from(["thaw".to_string()]));

view! {
    <Collapse value>
        <CollapseItem title="Leptos" key="leptos">
            "Build fast web applications with Rust."
        </CollapseItem>
        <CollapseItem title="Thaw" key="thaw">
            "An easy to use leptos component library"
        </CollapseItem>
    </Collapse>
}
```

### Accordion

Like an accordion.

```rust demo
view! {
    <Collapse accordion=true>
        <CollapseItem title="Leptos" key="leptos">
            "Build fast web applications with Rust."
        </CollapseItem>
        <CollapseItem title="Thaw" key="thaw">
            "An easy to use leptos component library."
        </CollapseItem>
        <CollapseItem title="Naive UI" key="naive-ui">
            "A Vue 3 Component Library. Fairly Complete. Theme Customizable. Uses TypeScript. Fast."
        </CollapseItem>
    </Collapse>
