Usage

1. Create a Language Switcher Menu

1. In the WordPress Block Editor (Site Editor or Navigation block), create a Navigation block with a submenu.

2. The parent menu item should display a placeholder: "LAN".

3. Add child menu items for each language (e.g., "EN", "ES").

4. Set the URL of each child to #.

5. Add the following CSS classes to each menu item:

   • Parent: .lang-switcher
   • Child for English: .lang-btn lang-en
   • Child for Spanish: .lang-btn lang-es
   • Repeat for other languages.

The JavaScript will automatically update the # links to point to the correct translated URLs.

2. Create Language-Specific Template Parts

1. Wrap blocks in a Group (or any container).

2. Add the following CSS classes to each group:

   • English version: lang-part-en lang-hidden
   • Spanish version: lang-part-es lang-hidden
   • Repeat for other languages.

3. Place these groups inside a template part (e.g., header, footer).

The plugin will automatically show only the group matching the current language.
