In MultiSelect, on selecting the dropdown menu items removing from menu and showing in selected lists
https://codesandbox.io/s/8qw3p?module=/example.js&file=/example.js
can we keep the selected items in dropdown menu itself and show selected.
can we keep Ocean in dropdown menu even it's selected.

Try adding the hideSelectedOptions={false} prop - that way the selected item remains in the dropdown menu.
Edited code taken from the CodeSandbox example:
import React from 'react';
import Select from 'react-select';
import { colourOptions } from './docs/data';
export default () => (
<Select
defaultValue={[colourOptions[2], colourOptions[3]]}
isMulti
name="colors"
options={colourOptions}
className="basic-multi-select"
classNamePrefix="select"
hideSelectedOptions={false}
/>
);
