If you are trying to overwrite the file menus.php via Child Theme and not getting results, please follow.
The menu is defined by the PHP class unmenu() in uncode/partials/menus.php, which isn’t a template file. To override the menus.php file, you only have to:
- Copy the entire class unmenu();
- Paste it into your Child Theme (in the file functions.php, for instance);
- Edit it as you prefer.
This new version will be executed instead of the original one. You will be able to add the changes you need to those new functions.
