QUESTION How to change menu active label?

[bacmid]

Instead of editing GS core files, I suggest you copy the whole get_navigation function to your theme's functions.php file (create it if it doesn't exist) with a different name (e.g. "my_get_navigation"), make the "uk-active" change there, and use this new function in your template. This way you will be able to upgrade GS without having to edit theme-functions.php again.

Thank you. I moved this function to theme's functions.php file.
