Answer 1

react-select provides a styling api which offers such customization. Each attribute in the object given to the styles prop is a function which is getting the current component state as a prop. The state also has props from the base component ( Select ).

<Select
    { ... }
    styles={{
        dropdownIndicator: (provided, state) => ({
            ...provided,
            transform: state.selectProps.menuIsOpen && 'rotate(180deg)'
        })
    }}
/>
