## Examples

### Labels

Ratings are commonly identified contextually, so labels aren't displayed. However, you should always provide one for assistive devices using the `label` attribute.

```html {.example}
<wa-rating label="Rate this component"></wa-rating>
```

### Maximum Value

Ratings are 0-5 by default. To change the maximum possible value, use the `max` attribute.

```html {.example}
<wa-rating label="Rating" max="3"></wa-rating>
```

### Precision

Use the `precision` attribute to let users select fractional ratings.

```html {.example}
<wa-rating label="Rating" precision="0.5" value="2.5"></wa-rating>
```

### Sizing

Use the `size` attribute to adjust the size of the rating.

```html {.example}
<wa-rating label="Rating" size="small"></wa-rating><br>
<wa-rating label="Rating" size="medium"></wa-rating><br>
<wa-rating label="Rating" size="large"></wa-rating>
```

For more granular sizing, you can use the `font-size` property.

```html {.example}
<wa-rating label="Rating" style="font-size: 2rem;"></wa-rating>
```

### Readonly

Use the `readonly` attribute to display a rating that users can't change.

```html {.example}
<wa-rating label="Rating" readonly value="3"></wa-rating>
```

### Disabled

Use the `disabled` attribute to disable the rating.

```html {.example}
<wa-rating label="Rating" disabled value="3"></wa-rating>
```

### Detecting Hover

Use the `wa-hover` event to detect when the user hovers over (or touch and drag) the rating. This lets you hook into values as the user interacts with the rating, but before they select a value.

The event has a payload with `phase` and `value` properties. The `phase` property tells when hovering starts, moves to a new value, and ends. The `value` property tells what the rating's value would be if the user were to commit to the hovered value.

```html {.example}
<div class="detect-hover">
  <wa-rating label="Rating"></wa-rating>
  <span></span>
</div>

<script>
  const rating = document.querySelector('.detect-hover > wa-rating');
  const span = rating.nextElementSibling;
  const terms = ['No rating', 'Terrible', 'Bad', 'OK', 'Good', 'Excellent'];

  rating.addEventListener('wa-hover', event => {
    span.textContent = terms[event.detail.value];

    // Clear feedback when hovering stops
    if (event.detail.phase === 'end') {
      span.textContent = '';
    }
  });
</script>

<style>
  .detect-hover span {
    position: relative;
    top: -4px;
    left: 8px;
    border-radius: var(--wa-border-radius-m);
    background: var(--wa-color-neutral-fill-loud);
    color: var(--wa-color-neutral-on-loud);
    text-align: center;
    padding: 4px 6px;
  }

  .detect-hover span:empty {
    display: none;
  }
</style>
```

### Custom Icons

You can provide custom icons by passing a function to the `getSymbol` property.

```html {.example}
<wa-rating label="Rating" class="rating-hearts" style="--symbol-color-active: #ff4136;"></wa-rating>

<script type="module">
  const rating = document.querySelector('.rating-hearts');

  await customElements.whenDefined("wa-rating")
  await rating.updateComplete

  rating.getSymbol = () => '<wa-icon name="heart" variant="solid"></wa-icon>';
</script>
```

### Value-based Icons

You can also use the `getSymbol` property to render different icons based on value.

```html {.example}
<wa-rating label="Rating" class="rating-emojis"></wa-rating>

<script type="module">
  const rating = document.querySelector('.rating-emojis');

  await customElements.whenDefined("wa-rating")
  await rating.updateComplete

  rating.getSymbol = value => {
    const icons = ['face-angry', 'face-frown', 'face-meh', 'face-smile', 'face-laugh'];
    return `<wa-icon name="${icons[value - 1]}"></wa-icon>`;
  };
</script>
```
