Taxomony menu - show all, vocabulary link are disabled
I am currently working on an ecomerce project and faced same issue. This helped https://www.youtube.com/watch?v=iBdVW7fC2Tg me so I recommend watching it, For the listing I have used drupal nice menus module. You can use it from https://drupal.org/project/nice_menus. In my project, listing is now working fine and I have 4 different menu items with their respective sub-categories.


If you still face any issues I will be available to help!
