Do not split the defaultValueArr. Use below code instead: Details.map((Det)=>{ Det.user_id. split( '' ).map((userID)=>{ defaultValueArr.push({ label: userID value: userID }); }); }); Splited values will be stored in defaultValueArr.

Check your data by printing it in console. I think you are getting multiple values in comma seperated string so you need to split the seperated string and form the defaultValue array . Or try to debug the code and check the length of Details array.

You need to fetch the value from API and form an array to pass in default Value: render(){ var defaultValueArr = []; Details.map((Det)=>{ defaultValueArr .push({ label: Det.user_id value: Det.user_id })}); return( defaultValue={defaultValueArr } placeholder={Select Mates} onChange={this.dropdownhandleChange} options={Dropdownlist.map(e => ({ label: e.Name value: e.Id}))} isMulti />) }
