Rather than destroying it, a much more simple approach would be attaching the key parameter to the MDBSelect component. The key could be the state of the selected value. Essentially, once the key changes, the component will be forced to unmount, then remount.

Here is a rough example using hooks. You will have to fill in additional logic to make it work.

const [selectedDrowndownVal, setSelectedDropdownVal] = useState(initialSelection);

const onDropdownSelect = key => { setSelectedDropdownVal(key[0]); }

<MDBSelect key={selectedDrowndownVal} options={YOUR_OPTIONS} selected={selectedDrowndownVal} label="Select a Value" getValue={onDropdownSelect} />
