Details of the navigation menus

Primary links

The primary links are set by the site administrator and are used for rapid and convenient access to frequently used links.

Search bar

The search bar will bring up content based on key words set automatically at the time content is created.

Main menu

This menu works like a typical taxonomic key. It permits the user to drill down about 3 levels at present. It must be manually updated by the site administrator as new content is added. It is a one parent---one-to-many children type of menu. Its advantage is that it is a familiar type of menu structure to most users. Its disadvantage is that it requires some knowledge to vectorborne diseases to use it. For example, if a user doesn't know that malaria is a mosquitoborne disease, it would be difficult to find malaria content in this type of menu.

Navigation menu

This menu is not a traditional type of menu. It permits the user to drill down as far as there are layers for any particular content. It is created automatically based on the headings selected by the content creator. It is a many parent-many children kind of menu. Its advantage is that the user does not need to know details of vectorborne diseases. The user can begin by selecting the disease name, the pathogen type, or the vector type. The disadvantage is that when the user makes the initial selection (e.g., diseases), all the content associated with any disease term is displayed. In practice, this usually means nearly all the content on the site. However, as the user drills down in this menu, the number of items displayed is filtered down to include only those included in the next selection, until finally the only items remaining will be those with identical taxonomic terms. A further disadvantage of this type of menu is that content is displayed in the order in which it was created, and currently, there is no way to arrange the content in any other way.
