This tutorial shows how to manage sidebars in Joomla 3.x. templates.
You can see a blog page below. We are going to add sidebars to this page.
In order to add sidebars you should add modules to aside-right and/or aside-left positions. Make sure that module is assigned to the menu item in Module assignment section. Screenshot shows module settings for aside-left position.
We have added right and left sidebars.
You can change width (number of columns) of sidebars in Template options. Go to Extensions->Template manager. In our case Default template is used for blog menu.
Open Layout tab. Adjust Sidebar width. Save the changes.
We have changed the sidebar width.
You can switch position of the module from aside-right to aside-left and vice versa by changing position of a particular module in the module manager.
