## Example

Dependencies:

```toml
vertigo = "0.10"
vertigo-forms = "0.1"
```

Example 1:

```rust
use vertigo::{computed_tuple, prelude::*};
use vertigo_forms::{Input, Select};

#[derive(Default)]
struct FormData {
    brand: Value<String>,
    model: Value<String>,
    year: Value<String>,
    engine: Value<String>,
}

#[vertigo::main]
fn render() -> DomNode {
    let form_data = FormData::default();

    let engine_types = Value::new(vec![
        "petrol".to_string(),
        "diesel".to_string(),
        "electric".to_string(),
    ]);

    let data_formatted = computed_tuple!(
        brand => form_data.brand,
        model => form_data.model,
        engine => form_data.engine,
        year => form_data.year
    )
    .map(|(brand, model, engine, year)| format!("{brand} {model}, {engine} ({year})"));

    dom! {
        <html>
            <head />
            <body>
                <form>
                    <p>"Brand: " <Input value={form_data.brand} /></p>
                    <p>"Model: " <Input value={form_data.model} /></p>
                    <p>"Year: " <Input value={form_data.year} /></p>
                    <p>"engine: " <Select value={form_data.engine} options={engine_types} /></p>
                </form>
                <p>
                    "Form data: " {data_formatted}
                </p>
            </body>
        </html>
    }
}
```

Example 2:

```rust
use vertigo::{bind_rc, prelude::*};
use vertigo_forms::form::{DataSection as DS, FormData, FormExport, ModelForm};

#[derive(Clone, Default, PartialEq)]
struct Car {
    brand: String,
    model: String,
    year: String,
    engine: String,
}

impl From<Car> for FormData {
    fn from(value: Car) -> Self {
        FormData::default()
            .add_top_controls()
            .with(DS::with_string_field("Brand", "brand", &value.brand))
            .with(DS::with_string_field("Model", "model", &value.model))
            .with(DS::with_string_field("Year", "year", &value.year))
            .with(DS::new("Engine").add_list_field(
                "engine",
                Some(&value.engine),
                vec!["petrol".into(), "diesel".into(), "electric".into()],
            ))
    }
}

impl From<FormExport> for Car {
    fn from(value: FormExport) -> Self {
        vertigo::log::info!("FormExport {}", value.get_string("engine"));
        Self {
            brand: value.get_string("brand"),
            model: value.get_string("model"),
            year: value.get_string("year"),
            engine: value.list_or_default("engine"),
        }
    }
}

#[vertigo::main]
fn render() -> DomNode {
    let car = Value::new(Car::default());

    let data_formatted =
        car.map(|car| format!("{} {}, {} ({})", car.brand, car.model, car.engine, car.year));

    let on_submit = bind_rc!(car, |new_model: Car| {
        car.set(new_model);
    });

    dom! {
        <html>
            <head />
            <body>
                <ModelForm model={car} {on_submit} params={} />
                <p>"Form data: " {data_formatted}</p>
            </body>
        </html>
    }
}
```

## Storybook App

### Prepare

Make sure you're using nightly version of rust:

* `rustup default nightly`

Install vertigo-cli:

* `cargo install vertigo-cli`

### Run

Build and run storybook in watch mode:

* `vertigo watch vertigo-forms-storybook`

Eventually terminal will let you know that app is available under `http://localhost:4444/`

If you want to play around with the code, the browser will automatically refresh after the project has been recompiled.

### Run example

To run the example in watch mode (it will run also on localhost:4444):
`vertigo watch vertigo-forms-example-form`
