A number of sidebar menus have different states depending on what has been selected. For example, when in a paper initially most of the 'Question Tasks' options are greyed out. These become active links once the user has selected a question. To do this all the links within 'Questions Tasks' are held in two <DIV> containers: one with the greyed out options and one with the active links. When the user selects a question JavaScript hides the grey <DIV> and shows the active link <DIV>.
The sidebar menus are contained within include files, brought in from /include/ directory. The language strings that are needed for the sidebar menu should be included in the 'parent' PHP file, they do not need their own separate language include file.
