Topic: Sidenav Example Code Does Not Work In Sample App

jammerxd2 priority asked 10 months ago


Expected behavior Sidenav opens properly

Actual behavior sidenav initially opens, then immediately hides and is not revealed when clicking the bars icon/button

Resources (screenshots, code snippets etc.) Source code taken from own demo and put into clean react js app

missing nav bar buttons

notice here that even though the bars are toggled, the sidenave does not appear. sidenave doesn't expand

How does one use both top nav and side nav in reactjs like the example code?

Here's my code snippet from the app.js which uses the exact demo code copy/paste apart from MDBDropdownLink changing to MDBDropdownItem link:

    import logo from './logo.svg';
import './App.css';

import React, { useState, useCallback, useEffect } from 'react';
import {
  MDBSideNav,
  MDBSideNavMenu,
  MDBSideNavItem,
  MDBSideNavLink,
  MDBSideNavCollapse,
  MDBIcon,
  MDBContainer,
  MDBNavbar,
  MDBInput,
  MDBInputGroup,
  MDBNavbarToggler,
  MDBNavbarNav,
  MDBNavbarItem,
  MDBDropdown,
  MDBDropdownToggle,
  MDBDropdownMenu,
  MDBDropdownItem,
  MDBBadge,
  MDBCollapse,
} from 'mdb-react-ui-kit';

export default function App() {
  const [collapseOpened, setCollapseOpened] = useState('accordionCollapse1');
  const [basicOpen, setBasicOpen] = useState(true);
  const [mode, setMode] = useState('side');
  const [showBasic, setShowBasic] = useState(false);

  const toggleAccordion = (value) => {
    value !== collapseOpened ? setCollapseOpened(value) : setCollapseOpened('');
  };

  const handleResize = useCallback(() => {
    if (!window.matchMedia('screen and (min-width: 1400px)').matches) {
      setMode('side');
      return setBasicOpen(false);
    }

    setMode('push');
    return setBasicOpen(true);
  }, []);

  useEffect(() => {
    handleResize();
  }, [handleResize]);

  useEffect(() => {
    window.addEventListener('resize', handleResize);

    return () => {
      window.removeEventListener('resize', handleResize);
    };
  }, [handleResize]);

  return (

Hi,

Thanks for the report. I can see, that there are some more differences from demo preview than just not working sidenav. I'm adding a task to fix it.

This should fix the sidenav, but the rest of the code still needs some changes.

const handleResize = useCallback(() => {
  if (!window.matchMedia('screen and (min-width: 1400px)').matches) {
    setMode('over');
    return setBasicOpen(false);
  }
  setMode('push');
  return setBasicOpen(true);
}, []);

&&

<MDBContainer fluid>
  <MDBNavbarToggler
    aria-controls='navbarSupportedContent'
    aria-expanded='false'
    aria-label='Toggle navigation'
    onClick={() => {
    // setShowBasic(!showBasic)
      setBasicOpen(!basicOpen);
    }}
