How to create "Selected tab" in Next.Js?

Time:01-13

I am trying to create selected tab in Next.Js.

The User will have the option to search for data it can be Users or Posts, what the user will search for will be selected by clicking on one of the buttons. enter image description here

Once the user clicks on the button the button will change background to blue.

enter image description here

However I can't make it to work properly, when the User clicks on the button the .Selected class gets added to the button but the button doesn't render the CSS.

import React, { MouseEventHandler, ReactElement, useState } from 'react'
import { PageWithLayout } from '../components/Layouts/LayoutConfig'
import MainLayout from '../components/Layouts/MainLayout'

import style from '../styles/Search.module.css'

const Search: PageWithLayout = () => {
  const [searchPosts, setPostsSearch] = useState < String > ();

  const setSearchOption = (searchFor: String) => {
    let searchOption = '';

    if (searchFor == 'POSTS') {
      searchOption = 'POSTS';
    } else {
      searchOption = 'USERS';
      let button = document.getElementById('usersOption') as HTMLElement;
      button.className  = style.Selected;
    }

    console.log(searchOption);
    setPostsSearch(searchOption);
  }

  return (
    <>
      <div className='pageContent'>
        <div className={style.SearchBarContainer}>
          <div className={style.SearchContainer}>
            <i className="fa-solid fa-magnifying-glass"></i>
            <input className={style.SearchBar} type={'text'} placeholder='Search...' />

          </div>
          <div className={style.SearchOptions}>
            <button id='usersOption' onClick={() => setSearchOption('USERS')}>Users</button>
            <button id='postsOption' onClick={() => setSearchOption('POSTS')}>Posts</button>
          </div>

        </div>
        <div className='SearchedContent'>

        </div>

      </div>
    </>
  )
}

Search.getLayout = function getLayout(page: ReactElement) {
  return (
    <MainLayout>
      {page}
    </MainLayout>
  )
}

export default Search

you can use searchOption data for className style

import React, { MouseEventHandler, ReactElement, useState } from 'react'
import { PageWithLayout } from '../components/Layouts/LayoutConfig'
import MainLayout from '../components/Layouts/MainLayout'

import style from '../styles/Search.module.css'

const Search: PageWithLayout = () => {

    const [searchPosts, setPostsSearch] = useState<String>();


    return (
        <>
            <div className='pageContent'>
                <div className={style.SearchBarContainer}>
                    <div className={style.SearchContainer}>
                        <i className="fa-solid fa-magnifying-glass"></i>
                        <input className={style.SearchBar} type={'text'} placeholder='Search...'/>

                    </div>
                    <div className={style.SearchOptions}>
                        <button id='usersOption' className={searchPosts === 'USERS' ? style.Selected : undefined } onClick={() => setPostsSearch('USERS')}>Users</button>
                        <button id='postsOption' className={searchPosts === 'POSTS' ? style.Selected : undefined } onClick={() => setPostsSearch('POSTS')}>Posts</button>
                    </div>

                </div>
                <div className='SearchedContent'>

                </div>

            </div>
        </>
    )
}

Search.getLayout = function getLayout(page: ReactElement){
    return(
        <MainLayout>
            {page}
        </MainLayout>
    )
}


export default Search

Just have a state for active searchOption and apply the class conditionally directly into the JSX.

const [activeSearchOption, setActiveSearchOption] = useState('USERS')

return (
        <>
          <div className='pageContent'>
            <div className={style.SearchBarContainer}>
              <div className={style.SearchContainer}>
                <i className="fa-solid fa-magnifying-glass"></i>
                <input className={style.SearchBar} type={'text'} placeholder='Search...'/>
               </div>
                <div className={style.SearchOptions}>
                  <button id='usersOption' className={activeSearchOption === 'USERS' ? 'active' : ''} onClick={() => setSearchOption('USERS')}>Users</button>
                   <button id='postsOption' className={activeSearchOption === 'POSTS' ? 'active' : ''} onClick={() => setSearchOption('POSTS')}>Posts</button>
                </div>
              </div>
                <div className='SearchedContent'>

                </div>
            </div>
        </>
    )
