The multi-language content filter allows you to display the same content in multiple languages within a single resource or activity, enhancing accessibility for international users.

🌐 Displaying Text in Multiple Languages

When this filter is enabled, Moodle scans for text wrapped in special <span> tags with lang and multilang attributes. Based on the user’s preferred language (set in their profile or browser), Moodle will display the matching language content.

🧩 How to Enable the Multi-language Filter

1. Navigate to:
   Site administration > Plugins > Filters > Manage filters
2. Find Multi-language content in the list.
3. From the dropdown, select “On” to activate the filter.
4. To apply the filter to headings as well, select “Content and headings” in the Apply to column.

⚠️ Enabling the filter for headings may slightly impact site performance.

✍️ How to Use in Course Content

1. While editing content (such as in a Label, Page, or Block), switch to HTML mode by clicking the [<>] icon.
2. Wrap each language version of your content in <span> tags using the format:

<span lang="en" class="multilang">Your content in English</span>
<span lang="de" class="multilang">Ihr Inhalt auf Deutsch</span>

3. Ensure that:
   • Tags are placed without other HTML or visible text between them
   • Only spaces, tabs, or newlines are allowed between language blocks
   • You start with the parent language if your site uses a child language pack (e.g., en before en_us)

✅ Correct Example:

<span lang="en" class="multilang">Welcome to the course</span>
<span lang="es" class="multilang">Bienvenido al curso</span>

📄 Example for Assignment Submission Agreement

You can also use the multi-language filter in Moodle-wide settings like submission agreements.

1. Go to:
   Site administration > Plugins > Activity modules > Assignment > Assignment settings
2. In the Submission statement field, add:

<span lang="en" class="multilang">This assignment is my own work...</span>
<span lang="fr" class="multilang">Ce devoir est le fruit de mon travail personnel...</span>

⚙️ How It Works (Behind the Scenes)

• Moodle scans the content for multilang blocks.
• For each block:
  1. If the user’s selected language matches a block → show that block.
  2. If not, but a matching parent language exists → show that.
  3. Otherwise → show the first block in the set.
• Text outside multilang blocks is always displayed.
