How to set a default value in react-select

I guess you need something like this:

const MySelect = props => (
<Select
    {...props}
    value = {
       props.options.filter(option => 
          option.label === 'Some label')
    }
    onChange = {value => props.input.onChange(value)}
    onBlur={() => props.input.onBlur(props.input.value)}
    options={props.options}
    placeholder={props.placeholder}
  />
);

I used the defaultValue parameter, below is the code how I achieved a default value as well as update the default value when an option is selected from the drop-down.

<Select
  name="form-dept-select"
  options={depts}
  defaultValue={{ label: "Select Dept", value: 0 }}
  onChange={e => {
              this.setState({
              department: e.label,
              deptId: e.value
              });
           }}
/>
