Hello,
Thank you very much for choosing our theme and for contacting us.
This manual contains instructions on how to create a mega menu: https://xtemos.com/docs/woodmart/create-menu-2/
Here you will find instructions on how to add a menu: https://xtemos.com/docs/woodmart/adding-menu-site/
The product category menu has additional options described here: https://xtemos.com/docs/woodmart/product-category-menu/
You can translate/rewrite all theme and plugin texts via PO file in WordPress. Here is a video tutorial that should help you translate your website texts with a Loco Translate plugin https://www.youtube.com/watch?v=D3NsDdMzsls&list=PLMw6W4rAaOgKKv0oexGHzpWBg1imvrval&index=3
Please check the video tutorial to see how to save the translation file correctly. You can remove the plugin and translations would remain. Also, translations would remain after each theme update.
In order to translate the Woocommerce strings, you need to create a separate translation in Loco > Plugins > Woocommerce in the same way as shown in the video.
If you have any questions please feel free to contact us.
Best Regards
