/>

/>

Controlled / Uncontrolled

The Select component has the same behaviors as a native HTML select and be both controlled and uncontrolled.

function () {
  const [value, setValue] = React.useState('Cookies');
  return (
    <Select
      label="Controlled"
      options={['Cookies', 'Pizza', 'Icecream']}
      value={value}
      onChange={(evt) => setValue(evt.currentTarget.value)}
    />
  );
}

<Select
  label="Uncontrolled"
  options={['Cookies', 'Pizza', 'Icecream']}
  defaultValue="Cookies"
  onChange={(evt) => console.log(evt.currentTarget.value)}
/>

Data Driven Selects

To fit common use cases, PMWCS Select provides a data driven method for rendering select menus. There are multiple formats you can pass data in, use the one that best fits your requirements. To make your label not float by default and to have an unselected blank value, set the placeholder prop to a blank string.

function Example() {
  // A controlled select Using a formatted array of options
  const options = [
    {
      label: 'Cookies',
      value: '1'
    },
    {
      label: 'Pizza',
      value: '2',
      /** Any additional items will be passed to the
         child ListItem as props */
      'aria-disabled': true,
      tabIndex: -1
    },
    {
      label: 'Icecream',
      value: '3'
    }
  ];

  return <Select label="Array" options={options} />;
}

<Select
  label="Object map"
  options={{ '1': 'Cookies', '2': 'Pizza', '3': 'Icecream' }}
/>

<Select
  label="Simple Array"
  placeholder="-- Select One --"
  options={['Cookies', 'Pizza', 'Icecream']}
/>

Manually Building the List

If you want full control over the child ListItems, you can manually build the list yourself.

<Select label="Manual" defaultValue="Cookies">
  <option value="Cookies">Cookies</option>
  <option value="Pizza">Pizza</option>
  <option value="Icecream">Icecream</option>
</Select>

Option Groups

Both native and enhanced Selects can contain option groups. Just nest additional options arrays in your data.

<Select
  label="Formatted"
  enhanced
  options={[
    {
      label: 'Dinner',
      options: [
        {
          label: 'Pizza',
          value: '2'
        }
      ]
    },
    {
      label: 'Dessert',
      options: [
        {
          label: 'Cookies',
          value: '1'
        },

        {
          label: 'Icecream',
          value: '3'
        }
      ]
    }
  ]}
/>

<Select label="Manually Built">
  <optgroup label="Dinner">
    <option value="Pizza">Pizza</option>
  </optgroup>
  <optgroup label="Dessert">
    <option value="Cookies">Cookies</option>
    <option value="Icecream">Icecream</option>
  </optgroup>
</Select>
