Hi @roggervalf ,
This is my code, I'm new in React so there might be some simple code.
But basicly the code is working fine, but the isSelected not worked for me.
Also the code file attached as TXT file

Thanks in advance.
`import { useEffect, useState, useContext } from 'react';
import { AppointmentPicker } from 'react-appointment-picker';

import { DatePickerCalendar } from 'react-nice-dates'
import 'react-nice-dates/build/style.css'
import './Appointments.css'
import { Container, Row, Col } from 'react-bootstrap'
import { getDay } from 'date-fns';
import AppointmentContext from '../Context/AppointmentContext';

function AppointmentsComp() {

const [lodaing, setLoading] = useState(false);
const [date, setDate] = useState(new Date(new Date().setHours(8, 0, 0, 0)));
const [days, setDays] = useState([[]]);

const modifiers = {
disabled: date => getDay(date) === 0 || getDay(date) === 6, // Disables Saturdays
}

const postContext = useContext(AppointmentContext)
const { error, appointments, getAppointments, removeAppointment, addAppointment } = postContext

useEffect(() => {
if (date != null) {
console.log("getting appointments")
setDays([

// useEffect(() => {

  );
  addCb(day, number, time, id);

Nice, I was playing around and it works when dates is not set by setDays, if you just declare the dates variables and just pass it into the react-appointment-picker, it should work

[naimgarzuzi]

I know that changing variable must be with use state, So I declared the setDays for changing the value of the days

Could you please change it in the sandbox to make it work?
I'll take a look after that to see how to do it without changing the state.

Thanks in advance.
