If you’re using Chrome, you can simulate a mobile browser, even if you’re on your desktop. While on the trooptrack page, press F12 on your keyboard and in the new windows that opens up, at the top,
just to the left of “Elements”, there is a button that shows a mobile device. Click that and your main browser screen will change to a mobile view. Then you can use the sub-menus.
Also, when you’re at the page that you want, you can click the same button to go back to regular, full size browser mode. You can alternate the view by toggling that button.
