</Canvas>

## Props

<ArgsTable of={HelpText} />

### Children

The `children` of the `HelpText` can be plain text or react nodes

  <Story id="components-componentlibrary-helptext--children" />
</Canvas>

```jsx
import { Size, IconColor } from '../../../helpers/constants/design-system';
import { HelpText, Icon, ICON_NAMES } from '../../component-library';

<HelpText>Plain text</HelpText>
<HelpText>
  Text and icon
      <Icon
        marginLeft={1}
        color={IconColor.inherit}
        name={ICON_NAMES.WARNING}

      />

  </HelpText>
  <HelpText color={Color.infoDefault} {...args}>
    This HelpText color is Color.infoDefault
