To separate your Blog form the rest of your Joomla based website, you should give it his, of her, own Menu module.
To do this you simply create a new Menu Module.
You can do this by going into your Administrator panel and choose Menu -> Menu Manager, you now see als the menu’s that are already in the system.
Click new, and Fill the two fields with the text of your choice, but please don’t use just Blog ! because this could get you into problems with some Sef components…
If you think your done, think again… the module is created, but not active yet.
You need to publish the module via the Module menu, Site Modules that is also where you decide to give it a place on your Site front-end.
As you can see, there are several options for you menu, just like all the other menu options.
From here on it is your choice on how to put the categories in from you Blogging section.
You did create a Blog section and categories? Otherwise read the beginning of the Blog categorie post again.
Create tables, or Blog layouts, within the menu as you see fit, but please be consistent enough for you site visitors!
Starting with you Blog section on the Frontpage
What if you really just want to use Joomla for Blogging… you don’t want to start with the standard Frontpage!
No, you want to show your your Blogging section and the latest Blog content from different categories, wouldn’t that be great?
And it is possible, with just one menu item, in the main menu…
Create a new menu item in the Main menu and link it to a Blog section choice, select all the Blogging categories to show and set the layout values you want to use.
Now move the just created menu item up the menu ladder until it is in first position , above Home!
Check the preview of your site and see how Joomla uses the First item in the main menu to start your site with…
You Blog section just as you wanted it.
For your menu, you get something like the menu below, where your visitors can directly go to their Blog category of intrest.
