# String: Capitalize first word

> Takes the given input string and converts the first letter to a capital. This only works when en phrase starts with a lowercase letter.

export const FormField = ({property, label, required = false, diType, uiPatterns, children}) => {
  const patterns = Array.isArray(uiPatterns) ? uiPatterns : uiPatterns ? [uiPatterns] : [];
  return <div style={{
    margin: '1.5rem 0'

      <div style={{
    display: 'flex',
    alignItems: 'baseline',
    flexWrap: 'wrap',

          {required ? 'Required' : 'Optional'}

};

Capitalises the first letter of a text value and leaves the rest of the value exactly as it is. Use this to tidy up labels, names, or short descriptions that should start with a capital, for example turning "wool scarf" into "Wool scarf". Only the very first character is changed, so the other words in the value keep their original casing.

This documentation describes: [Schema](/schemas/mapper/string-upper-first)

## Fields

This mapper has no settings. It always capitalises the first letter of the value.

## Sample data

```json theme={null}
{ "name": "wool scarf" }
```

Output:

  "prototype": "string-upper-first",
  "parameters": {}
}
