<p><strong>QBlocks Menu Sync for Polylang</strong> adds a “Duplicate Menu” panel to the WordPress Appearance > Menus screen. Clone any navigation menu — including all items, hierarchy, and settings — in seconds, with full Polylang multilingual support.</p>
<p>This plugin is not affiliated with Polylang or its developers. “Polylang” is a trademark of its respective owner; this plugin simply integrates with the Polylang plugin’s public API.</p>
<h4>Features</h4>
<ul>
<li><strong>One-click menu duplication</strong> — duplicate any menu with all items preserved</li>
<li><strong>Polylang integration</strong> — clone menus to one or more target languages in a single action</li>
<li><strong>Smart translation</strong> — automatically links to translated pages, posts, and taxonomy terms when available</li>
<li><strong>Fallback handling</strong> — keeps original linked objects when no translation exists</li>
<li><strong>Custom links</strong> — duplicated as-is with no changes</li>
<li><strong>Theme location assignment</strong> — optionally assign the cloned menu to any registered theme location</li>
<li><strong>Polylang-aware locations</strong> — assigns per-language location slots without affecting other languages</li>
<li><strong>Unique naming</strong> — auto-generates unique menu names to prevent conflicts</li>
<li><strong>Source language badge</strong> — clearly shows which language you are cloning from</li>
<li><strong>Secure</strong> — nonce verification, capability checks, input sanitization, and output escaping throughout</li>
</ul>
<h4>How It Works</h4>
<ol>
<li>Go to <strong>Appearance > Menus</strong></li>
<li>Select the menu you want to duplicate</li>
<li>Open the <strong>Duplicate Menu</strong> panel (above the menu structure)</li>
<li>Choose target languages (if Polylang is active)</li>
<li>Optionally set a custom name and assign theme locations</li>
<li>Click <strong>Duplicate Menu</strong></li>
</ol>
<h4>Polylang Support</h4>
<p>When Polylang is active, the plugin detects the source menu’s language and offers all other active languages as targets. For each target language:</p>
<ul>
<li>Pages and posts are automatically linked to their translation</li>
<li>Categories and custom taxonomy terms are linked to their translation</li>
<li>If no translation exists, the original object is kept as a fallback</li>
<li>Custom links are duplicated unchanged</li>
<li>The new menu is assigned the correct Polylang language</li>
</ul>
<h4>Without Polylang</h4>
<p>The plugin works as a simple menu duplicator — no language features, just a clean copy of the menu and all its items.</p>

<h4>What is «Polylang Theme Strings» and what for is it?</h4>
<p>This plugin gives additional features to the plugin Polylang. It automatically scans all templates files and scripts of the active WP theme (and all plugins) for available strings that can be translated. For example:</p>
<ul>
<li><code>pll__('...');</code></li>
<li><code>pll_e('...');</code></li>
</ul>
<p>and adds them to the Polylang registery, after what you can manage the translation of finded strings using the administration panel. It will make your life easier for the development of multilanguage’s projects, because you will not need to enter the needed strings to translate manually – the plugin will do all the work for you.<br />
Don’t forget that in the example are described the PHP-function calls, that is why they have to be inside of PHP-tags.</p>
<h4>How works «Polylang Theme Strings»?</h4>
<p>You have to install the plugins «Polylang» and «Polylang Theme Strings» on your multilanguage WordPress CMS project and they must be both active. When you are in the settings of plugin (Polylang) in the tab «Strings translation» the «Polylang Theme Strings» scans automatically the active theme of your project, find all the code strings that needed to be translated, adds them to the register, displays them on that page and gives to user the ability to translate these strings.</p>
<p>Like you can see, the «Polylang Theme Strings» is perfectly integrate with the «Polylang» plugin and works in automatically mode – it is comfortable, simple, and useful!</p>
<p>From version 4.0 «Polylang Theme Strings» got settings page where you can configure the search strings-translations more deeply.</p>
