All content items must be either directly or indirectly linked to a menu item in order to show on the front end of your site.  A content item can be linked to a menu item while in the development stage, or it can be linked after the content item is saved.

Content can be linked to a menu item indirectly through a category or section if that category/section is linked to a menu item.

 

Go to:    Menu > Mainmenu (or whatever menu you would like to create the link in)

Click the New button.

You will see a variety of options available to you.  Select the type of menu item you would like to create. For example; for a static content item you will likely want to choose Link - Static Content. If you have a series of blogs saved in a blog category, you will want to choose, Blog - Content Category.

Click on the menu link of choice.  An Add Menu Item dialog box will come up.   Type in a menu name in the Name field.   Then select the  content item you created for this menu item from the list.

Click the Save button.

Go to the front end of your site.  Refresh to see your changes.  Feel free to experiment. If the link doesn't turn out the way you want it to, simply trash it and create a new one.
