Show the selected option as the first option in the select dropdown?

I am using react-select to show a list of users in a dropdown. I want it to always show the selected element as the first element in the list. Is there native support for this?

Example:

In the following image, since Green is selected, I want Green to appear at the top of the list before Ocean

enter image description here

You can pass an initialize callback to useState to sort the options array for the first time and put the defaultValue on top:

function sortOptions(options, selectedValue) {
  return options.sort((a, b) => {
    if (a === selectedValue) return -1;
    if (b === selectedValue) return 1;
    return 0;
  });
}

const defaultValue = colourOptions[5];
const [options, setOptions] = React.useState(() =>
  sortOptions(optionsProp, defaultValue)
);

return (
  <Select
    defaultValue={defaultValue}
    onChange={(value) => setOptions(sortOptions(optionsProp, value))}
    name="colors"
    options={options}
  />
);

Try this Code :

  const [options, setOptions] = useState([
    { label: "Blue", value: "Blue" },
    { label: "Red", value: "Red" },
    { label: "Yellow", value: "Yellow" },
    { label: "Green", value: "Green" },
    { label: "Pink", value: "Pink" },
    { label: "White", value: "White" },
    { label: "Brown", value: "Brown" }
  ]);
  const [value, setValue] = useState("Select");
  function handler(e) {
    setValue(e);
    let newOptions = [];
    newOptions.push({ label: e, value: e });
    for (let i in options) {
      if (options[i].value !== e) {
        newOptions.push(options[i]);
      }
    }
    setOptions(newOptions);
  }
  return (
    <div className="App">
      <Select
        name="colors"
        defaultValue={value}
        options={options}
        onChange={(e) => handler(e.value)}
      />
    </div>
  );
