If you want to hide the pathway breadcrumb on the frontpage of your Mambo web site you simply have to wrap it in a snippet of PHP code.
Here is an example of the code:
The Mambo frontpage is always called by com_frontpage. The pathway (also known as "breadcrumbs")is a Mambo function called mosPathWay. What this code does is tell Mambo that if the content is using com_frontpage then do not output the mosPathWay code. If the content is not using the variable option of com_frontpage then the pathway will be displayed.
