I have set up Select component as follow
<Select
styles={customStyles}
defaultValue={{ label: t('Text to be translated'), value: 'all' }}
components={{
IndicatorSeparator: () => null,
}}
isSearchable={isSearchable}
options={[
{ value: 'val1', label: t('text 1') },
{ value: 'val2', label: t('text 2') },
{ value: 'val3', label: t('text 3') },
]}
onChange={handleSelectChange}
isDisabled={disabled}
/>
my defaultValue is translated only on first load of component. Changing language does not affect in any ways. Text is show in language that was chosed on initial load. But fun fact - options are translated with no problem at all
