Macro define_elements 

macro_rules! define_elements {
    ($($tokens:tt)*) => { ... };
}

Define typed custom elements (and their typed attributes) for use in rsx!.

Reach for define_elements! when your app needs project-specific element names or attributes that should type-check just like the built-in Dioxus HTML elements. Each element becomes a typed builder, and each listed attribute becomes a typed method you can set in rsx!.

Element and attribute identifiers are written in Rust (snake_case or camelCase). Use #[element(name = "...")] / #[attr(name = "...")] to control the rendered HTML name when it differs from the Rust identifier - for example to emit a hyphenated custom-element tag or a data-* attribute.

Example

use dioxus::prelude::*;

dioxus::html::define_elements! {
    // Renders as `<analytics-panel>` even though the Rust name is `analyticsPanel`.
    #[element(name = "analytics-panel")]
    analyticsPanel {
        metric,
        // Renders as the `data-region` attribute.
        #[attr(name = "data-region")]
        region,
    }
}

fn app() -> Element {
    rsx! {
        analyticsPanel {
            metric: "conversion-rate",
            region: "north-america",
            "Revenue dashboard"
        }
    }
}
