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 its internationalization framework. This framework allows you to translate text anywhere in the template. For demonstration purposes, the template includes translation for the navigation menu, but you can extend this functionality across the entire template.

1. Add or Update Language Options in the Navbar Dropdown

   You can easily add or modify language options in the navigation bar. For instance, to add the Arabic language, use the following code snippet. Ensure you set the language in the data-language attribute and specify the text direction (e.g., rtl for right-to-left)
   Copy

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

   This template uses the Flag Icons library, allowing you to add any country’s flag to the dropdown. Simply choose the appropriate flag icon for the language.

2. Manage Translation Files

   The translation files are located in the /assets/json/locales/ folder. Each file contains key-value pairs for words or phrases to translate. You can:

   • Add new key-value pairs to an existing language file.
   • Create a new language file for additional languages.

   When using translations, include the data-i18n attribute in the corresponding HTML tag. For example:

   Copy

   <span data-i18n="Apple">Apple</span>

3. Set the Default Language in Configuration

   To set the default language, modify the lang value in the config.js file. For example, set it to English ('en') as shown below:

   Copy

   if (typeof TemplateCustomizer !== 'undefined') {
     window.templateCustomizer = new TemplateCustomizer({
       displayCustomizer: true,
       lang: localStorage.getItem('templateCustomizer-' + templateName + '--Lang') || 'en', // Set default language here
       // defaultPrimaryColor: '#D11BB4',
       // defaultSkin: 1,
       // defaultTheme: 'system',
       // defaultSemiDark: true,
       // defaultContentLayout: 'wide',
       // defaultHeaderType: 'static',
       // defaultMenuCollapsed: true,
       // defaultNavbarType: 'static',
       // defaultTextDir: 'rtl',
       // defaultFooterFixed: false,
       // defaultShowDropdownOnHover: false,
       controls: [
         'color',
         'theme',
         'skins',
         'semiDark',
         'layoutCollapsed',
         'layoutNavbarOptions',
         'headerType',
         'contentLayout',
         'rtl'
       ]
     });
   }

4. Initialize Internationalization in main.js

   The internationalization setup is defined in the main.js file. Below is the initialization code:

   Copy

   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/.json'
         },
         returnObjects: true
       })
       .then(function (t) {
         localize();
       });
   }

   Key Parameters:

   • lang: Sets the default language. Here, the lang value is retrieved from config.js.
   • fallbackLng: Specifies the fallback language if the selected language file is unavailable.
   • loadPath: Defines the file path for the language JSON files.

5. Modify the template-customizer.js to Support the New Language
