Pass value as string instead of object

[oktalk]

Is there any way to pass in the value as a string instead of the object of my option? My option looks like this: ['am', 'pm']. I set the string value in my state and update the Select value with the string. However, it now shows that nothing is selected because the value is expecting an object like {label: 'am', value: 'am'}.

Any way I can avoid this issue and just pass in a string as the value?
