Using as a controlled select

Controlled components in React are those in which form data is handled by the component’s state.

For using the Select as a controlled component, you need to:

• Pass one of the options as the value property, with this property it will already be a controlled component;
• Pass a onChange handler, so you can use it to update the value of value;

Hide code
function SelectControlledExample() {
  const [selectValue, setSelectValue] = useState('optionOne');
  const handleOnChange = (event) => setSelectValue(event.target.value);

  return (
    <Select
      id="optionSelect-controlled"
      name="optionSelect-controlled"
      value={selectValue}
      onChange={handleOnChange}
    >
      <Select.Option value="optionOne">Option 1</Select.Option>
      <Select.Option value="optionTwo">Long Option 2</Select.Option>
    </Select>
  );
}
function SelectControlledExample() {
  const [selectValue, setSelectValue] = useState('optionOne');
  const handleOnChange = (event) => setSelectValue(event.target.value);

  return (
    <Select
      id="optionSelect-controlled"
      name="optionSelect-controlled"
      value={selectValue}
      onChange={handleOnChange}
    >
      <Select.Option value="optionOne">Option 1</Select.Option>
      <Select.Option value="optionTwo">Long Option 2</Select.Option>
    </Select>
  );

Using as an uncontrolled select

Uncontrolled components are those for which the form data is handled by the DOM itself. “Uncontrolled” refers to the fact that these components are not controlled by React state.

You can use the Select as an uncontrolled component, for that you can:

• Set the defaultValue property, it will ensure that the select value can be altered normally.
• Don't set the value property as it will make the select controlled.

Hide code
function SelectUncontrolledExample() {
  return (
    <Select
      id="optionSelect-uncontrolled"
      name="optionSelect-uncontrolled"
      defaultValue="optionOne"
    >
      <Select.Option value="optionOne">Option 1</Select.Option>{' '}
      {/* This option would be selected by default */}
      <Select.Option value="optionTwo">Long Option 2</Select.Option>
    </Select>
  );
}
function SelectUncontrolledExample() {
  return (
    <Select
      id="optionSelect-uncontrolled"
      name="optionSelect-uncontrolled"
      defaultValue="optionOne"
    >
      <Select.Option value="optionOne">Option 1</Select.Option>{' '}
      {/* This option would be selected by default */}
      <Select.Option value="optionTwo">Long Option 2</Select.Option>
    </Select>

Content guidelines

• Use Select to present many different options in one component
• When you have only a few options try to show them all at once, using Radio.
• Use Select in Forms
• Order the list of options in a logical way, so it make sense for the user
• Don't use Select for a very long list of options, instead for those cases use Autocomplete
• Options should be written in sentence case (the first word capitalized, the rest lowercase).
• Options should be labeled in a clear way, so it's obvious what the option will do

Select vs Dropdown

1. Dropdown menus are typically used for navigation or command menus, where an action is initiated based on the selection.
2. Select is a type of input, where the user is choosing one option from the list, typically used in Forms.

Accessibility

• To ensure Select meets accessibility keyboard standards, set the name and id properties.
• The component should be wrapped in a <FormControl as="fieldset"> and set a label via <FormControl.Label as="legend">.
• Make use of <FormControl.HelpText> and <FormControl.ValidationMessage> to provide further context
• For more information about validation and controlling form fields, please refer to FormControl.

Keyboard Usage

• Use the “arrow keys (“←”, ”↑”. “→”, and “↓”) + enter” to send the form.
• To switch between options with the keyboard, use the “tab + space” and the arrow keys.
