The scheduler component does not work in Internet Explorer. We need to support IE 11 for our costumers. On the Kendo React example page I get an error that the  'object does not support property or method 'entries'.  In the code we're developing the error is similar, but refers to 'forEach' instead of entries.

I'm seeing a bug in TreeList which seems to be related to how locked column positions are being set.  The issue I'm seeing is when I scroll to the right the columns either overlap of have a gap between them.  See image below.

I also created a demo that demonstrates this issue: https://stackblitz.com/edit/react-lwp4ua?file=app%2Fmain.jsx

UPDATE: This is live code I prepared for you: https://stackblitz.com/edit/react-ts-dhhsaz?file=index.tsx

I get error:

 Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app

But error appears to be inside KendoDrawer component. I can't figure out what is wrong. This is my component:

import React, { useState } from 'react';
import { withRouter, useLocation, useHistory } from 'react-router-dom';

import { Drawer, DrawerContent } from '@progress/kendo-react-layout';
import { Button } from '@progress/kendo-react-buttons';

export const SidebarDrawer = (props:any) => {

    const items = [
        { text: 'Povezivanje', icon: 'k-i-inbox', selected: true, route: '/povezivanje' },
        { separator: true },
        { text: 'Notifications', icon: 'k-i-bell', route: '/notifications' },
        { text: 'Calendar', icon: 'k-i-calendar', route: '/calendar' },
        { separator: true },
        { text: 'Attachments', icon: 'k-i-hyperlink-email', route: '/attachments' },
        { text: 'Favourites', icon: 'k-i-star-outline', route: '/favourites' }

    const [expanded, setExpanded] = React.useState(true);
    const [position, setPosition] = React.useState(true);
    const [selectedId, setSelectedId] = React.useState(items.findIndex(x => x.selected === true));

    let positionMode = position ? 'start' : 'end';

    const handleSelect = (ev:any) => {

    const handleClick = () => { setExpanded(prevState => !prevState); };

    const handleChange = () => { setPosition(prevState => !prevState); };

    const drawerProps = {
        expanded: expanded,
        position: positionMode,
        mode: 'push',
        items: items.map(
            (item, index) => ({ ...item, selected: index === selectedId })),

        onSelect: handleSelect,

    return (
        <Drawer {...drawerProps}>
        </Drawer >


export default withRouter(SidebarDrawer);

And this is how I use it inside App component:

import React, { useState } from 'react';
import { hot } from 'react-hot-loader';
import { Button } from '@progress/kendo-react-buttons'
import { Grid, GridColumn, GridDetailRow, GridToolbar } from '@progress/kendo-react-grid';
import '@progress/kendo-theme-bootstrap/dist/all.css';

import 'bootstrap/dist/css/bootstrap.min.css';
import { Drawer, DrawerContent } from '@progress/kendo-react-layout';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';

import urlConstants from 'ClientApp/constants/urlConstants'
import { Connecting } from '../containers/connecting/Connecting';
import SidebarDrawer from 'ClientApp/components/SidebarDrawer/SidebarDrawer';

export const App: React.FC = () => {

    return (
                        <Route exact={true} path="/" component={Connecting} />


export default hot(module)(App);
