SUB_DOMAIN

Add subdomain name so script starts only on specific subdomain. If you want script turned off, leave it `undefined` or just `""`. Make sure there is no space between quotes, otherwise script will work no matter subdomain name.

HIDDEN_CONTENT

Here you can add specific website parts to be hidden. Class / ID has to be unique, otherwise it will hide all content that match written class/id. 

REDIRECT_TO_MAIN_PAGE_AFTER_REGISTRATION

Set this to "true" if you want that after complete registration user will be redirected to your main page and hider script disabled. There is one downside with it - after redirect user will have to re-login to his account.

REDIRECT_TO_MAIN_PAGE_AFTER_LOGIN

Set this to "true" if you want that after login user will be redirected to your main page and hider script disabled. There is one downside with it - after redirect user will have to re-login to his account.

HIDDEN_GAMES

Here you can add games that you want to be hidden in header. If you pass `'undefined'` to hidden games array it will hide all expandable menus. It is important to know that if you want the best experience with the script you should add `'.left-menu.side-menu-toggle-wrapper'` to HIDDEN_CONTENT array, to hide mobile side menu, since this script can't handle it.
