## Input help

Use an input helper to display additional information about a form element. The text label will appear once a user hovers over the helper. To add an input helper, use the `.form-help` class.

```html
<span
  class="form-help"
  data-bs-toggle="popover"
  data-bs-placement="top"
  data-bs-html="true"
  data-bs-content="<p>...</p>"
  >?</span
>
```

Look at the example below to see how the input help works:

<Example>
<div> <label class="form-label"> ZIP Code <span class="form-help" data-bs-toggle="popover" data-bs-placement="top" data-bs-html="true" data-bs-content="<p>ZIP Code must be US or CDN format. You can use an extended ZIP+4 code to determine address more accurately.</p><p class='mb-0'><a href=''>USP ZIP codes lookup tools</a></p>" >?</span > </label> <input type="text" class="form-control" placeholder="Your ZIP Code" /> </div>
</Example>

## Required field

Use the `.required` class to indicate that a field is required. It will add a red asterisk to the label.

<Example>
<div> <label class="form-label required">Required</label> <input type="text" class="form-control" name="..." placeholder="Required..." /> </div>
</Example>

## Form hint

Use a form hint to provide users with additional information about a form element. The text will appear below the input field. To add a form hint, use the `.form-hint` class.

```html
<div class="form-hint">We'll never share your email with anyone else.</div>
```

Look at the example below to see how the form hint works:

<Example>
<div> <label class="form-label">Email address</label> <input type="email" class="form-control" placeholder="Enter your email address" /> <FormHint>We'll never share your email with anyone else.</FormHint> </div>
</Example>

## Additional info inside label

Use the `.form-label-description` class to add additional information to the label. The text will appear next to the label. You can use it to add for example a character counter.

<Example>
<div> <label class="form-label">Textarea <span class="form-label-description">56/100</span> </label> <textarea class="form-control" name="" rows="3" placeholder="Content.."></textarea> </div>
</Example>
