WordPress Widgets add content and features to your sidebars. Examples are the default widgets that come with WordPress; for post categories, tag clouds, navigation, search, etc. Plugins will often add their own widgets.

Widgets were originally designed to provide a simple and easy-to-use way of giving design and structure control of the WordPress Theme to the user, which is now available on properly “widgetized” WordPress Themes to include the header, footer, and elsewhere in the WordPress design and structure.

Now that we have some idea what widgets are, let’s have a look at what they can do and where they can be found in Opus Primus.

To start with, your readers will not see anything in the various widget areas unless you add content to them first. There are currently 12 widget areas available as of this writing.

The Widget Areas:

  • There are three (3) widget areas in the “header” that will appear above the top menu spanning the width of the theme.
  • There are three (3) widget areas in the “footer” that will appear below all other content and span the width of the theme.
  • There is a widget area directly above the main “content” area.
  • There is also a widget area directly below the main “content” area.
  • There are four (4) widget areas in the sidebar on the left side of the theme. Content placed in these areas will affect the theme layout.

The Sidebar widgets may need a bit more explanation. This is how they work:

  • If no sidebar widget areas are active, the web site will be one column.
  • If a widget is used in one of the first two sidebar areas ONLY, the web site will be two columns with the sidebar on the right.
  • If a widget is used in one of the second two sidebar areas ONLY, the web site will be two columns with the sidebar on the right.
  • If a widget is used in at least one of the first two sidebar areas and in at least one of the second two sidebar areas, the web site will be three columns with the sidebars on the right. In these cases: the first column will contain the site’s main content; the second column will contain the content displayed by those widgets used in the First and Second Sidebar Areas; and, the third column will contain the content displayed by those widgets used in the Third and Fourth Sidebar Areas.

Additional sidebar areas can be defined and attached to any of the many available hooks in the theme. Their location and functionality will only be limited by the imagination of the developers.
