Yes. Before you remove it, confirm the following important points.

• Many third-party plugins (For example, Select2, Block UI, jQuery-idletimer, Typeahead etc..) are still using jQuery and they are very useful. Due to that we can't remove it. But if you are not using those libraries you can remove jQuery.
• The navbar search functionality also depends on jQuery plugin (Typeahead), it will stop working if you remove jQuery.

If you are fine with the above points, then proceed with removing jquery.js from HTML.
Also, remove jQuery plugin usage from main.js. Search for the Removed following code if you don't wish to use jQuery and remove the code.

Sneat Use i18next as internationalization-framework. For demo purposes in this template, we're just translating the menu (navigation), but you can use translation anyware in this template.

1. Add/update language option to the navbar dropdown easily.
   To add the Arabic language, refer the following code. Don't forget to set language to data-language attribute. This template use Flag Icons flag library, use any country flag icon from it.
   Copy

   <li>
     <a class="dropdown-item" href="javascript:void(0);" data-language="ar" data-text-direction="rtl">
       <span class="align-middle">Arabic</span>
     </a>
   </li>

2. assets/json/locales/ folder contain different languages translation files. It contains Key, Value pairs for each word to translate. You can add more Key, Value pairs or create a new language file.
3. Also, add that Key to data-i18n attribute to HTML tag. For example, <span data-i18n="Apple">Apple</span>
4. Search lang in config.js and set the default language here. For ex: 'en'.

if (typeof TemplateCustomizer !== 'undefined') {
  window.templateCustomizer = new TemplateCustomizer({
    cssPath: assetsPath + 'vendor/css' + (rtlSupport ? '/rtl' : '') + '/',
    themesPath: assetsPath + 'vendor/css' + (rtlSupport ? '/rtl' : '') + '/',
    displayCustomizer: true,
    lang: localStorage.getItem('templateCustomizer-' + templateName + '--Lang') || 'en', // Set default language here
    // defaultTheme: 2,
    // defaultStyle: 'system',
    // defaultTextDir: 'rtl',
    // defaultContentLayout: 'wide',
    // defaultHeaderType: 'static',
    // defaultMenuCollapsed: true,
    // defaultNavbarType: 'sticky',
    // defaultFooterFixed: false,
    // defaultShowDropdownOnHover: false,
    controls: ['rtl', 'style', 'headerType', 'contentLayout', 'layoutCollapsed', 'layoutNavbarOptions', 'themes']
  });
}
              

5. Internationalization section in main.js. It contains the following code.

if (typeof i18next !== 'undefined' && typeof i18NextHttpBackend !== 'undefined') {
i18next
  .use(i18NextHttpBackend)
  .init({
    lng: window.templateCustomizer ? window.templateCustomizer.settings.lang : 'en',
    debug: false,
    fallbackLng: 'en',
    backend: {
      loadPath: assetsPath + 'json/locales/{{lang}}.json'
    },
    returnObjects: true
  })
  .then(function (t) {
    localize();
  });
}

• lang: use this parameter to set default language In our case we're using window.templateCustomizer.settings.lang from config.js file. If the default translation language file is not available then it will use fallbackLng automatically.
• loadPath: Set the language JSON file path.
