PrestaShop mega menu not working (add rows)

You have a PrestaShop TM Mega Menu plugin, and you are probably reading this post because you are facing problems with your top menu, whether on mobile or desktop version. The most common issues are the following:

a. You cannot create a new link or a sub-menu, because TM mega menu module is not adding rows, or

b. You can’t update your existing drop-down menu, or

c. Your PrestaShop module is not working on mobile, and you cannot modify your current top menu on your header, or

d. You want to edit your PrestaShop TM Mega Menu module (tmmegamenu), and you realize, that your sub-menus get disappeared, every time you edit a row.

2-steps solution to repair the error of your mega menu and override bugs

The technical seo mega menu quick solution, which is possibly the fix for your problem, is to integrate the JavaScript file named back.js inside your header.tpl. Instead of calling the specific .js file directly from your Mega Menu module, actually through tmmegamenu.tpl file, try to include it just above the ending </head> tag.

Step.1
In other words, locate the tmmegamenu.php file of the module. You will find it under /httpdocs/modules/tmmegamenu. Before doing anything, you are recommended to create a backup of your e-shop, saving both filesystem and DB for future reference, in case needed. Next, set as comment the following line in tmmegamenu.php , as written hereafter:

 //$this->context->controller->addJS($this->_path.'views/js/back.js');

Step.2
Next, locate the header.tpl file normally under admin/yourtheme/default/template/header.tpl . At the end of the head section, add the following line, before the </head> HTML tag:

<script type="text/javascript" src="../modules/tmmegamenu/views/js/back.js"></script>

The header.tpl file is a part of PrestaShop themes and modules. It defines the HTML structure and layout for the header section in the PrestaShop Back Office or Front Office.

Important notes, depending on your PrestaShop version and setup.

You can locate this file in one of the following locations:

1. Default Back Office Header

If it pertains to the Back Office (admin panel), the header.tpl file is often part of the Back Office theme files:

Path: /admin/themes/default/template/header.tpl

2. Default Front Office Header

If it is part of the Front Office (shop interface for customers), the file resides in the active theme directory:

Path: /themes/<your-theme-name>/header.tpl .

Replace <your-theme-name> with the name of your current theme.

3. Module-Specific Header

Some modules might override or include their custom header.tpl files to modify the header for specific pages:

Path: /modules/<module-name>/views/templates/front/header.tpl .

Replace <module-name> with the specific module’s directory name.

How to Locate the PrestaShop Files you need, to Fix TM Mega Menu

If you cannot find the file in the above locations, you can:

Search the PrestaShop Files: Use a file search tool to look for header.tpl.
Override System: Check if your theme or module has overridden the core template by looking in override folders:
/override/controllers/admin/
/override/controllers/front/
