The Natural Numbers

The natural numbers {0, 1, 2, 3, 4, . . .} are used for counting, ordering and labelling.

Prime Numbers

Prime Numbers can be divided only by 1 and itself, without leaving a remainder.<

  • Christian Goldbach - In 1742 conjectured that every even integer greater than 2 could be written as the sum of two primes. This conjecture remains unproven.


Integers include the natural numbers and negative numbers.

Step 1 - Navigation

For this example, we are going into the primary links menu but the technique is exactly the same for all menus in the Administrative area.

Step 2 - The Menu Admin Area

You will then be transported to the Menu Manager for primary links. At this point, you can do two things. The first is to edit an existing menu item, which we will be doing in this tutorial or create a New menu item to be subordinate to an existing item. Click on the item you want to be part of the dropdown menu.

Step 3 - Assigning a Parent Item

You can now assign the content item to the mainmenu item in which you want to be in the dropdown menu. Identify the "Parent Item" section of the manager. You will select the item in which you wish to be the parent and the source of the dropdown menu.
