Last week I was approached with an issue from one of my collegues "the magento category navigation not displaying, what am I doing wrong?".  After hours on hours trying different techniques, I finally realized how easy and simple it was to display the navigtion.

Below are the steps you should follow if your navigation isn't displaying on your magento website:

• Make sure your categories are a sub-category of the Default (Root) Category
  Out-of-the-box, Magento creates your default category (make sure you don't delete this).  When you start to build out your navigation, create sub-categories and place them under your Default (Root) Category.

Go under CATALOG / MANAGE CATEGORIES / then select ADD SUBCATEGORY, and there you have it in a nutshell!
