When dealing with your post archives there are three main options, you'll want to make note of. These options can be set site-wide from your theme options, or individually for specific category and tag archives.
- Sidebar layout — How sidebars display on post archives. See article, Sidebar Layouts.
- Post display — The style posts display on post archives. See article, Post Displays.
- Info boxes — Displaying title and description for category and tag archives
Site-Wide Archive Options
From Appearance > Theme Options > Layout > Sidebar Layouts, you can select the default sidebar layout that will be applied to all of your post archives.
And from Appearance > Theme Options > Content > Archives, you'll find the rest of your site-wide post archive options. Here, you can select the post display for all post archives. And then for category and tag archives, you can select if you want the info boxes (i.e. title and description) to display.
Individual Category and Tag Archive Options
When editing an individual category or tag, all three of these site-wide options can be overridden.
Info Boxes — Displaying Title & Description on Archives
When viewing a post archive, by default, you won't see the title or description displayed above the listing of posts. However, you can display this information for category and tag archives using Info Boxes.
To enable Info Boxes site-wide across all category and tag archives, you can do this from your site-wide archive options on your theme options page.
While all categories you create through WordPress are going to have a title, by default, they will not have a description. So, remember to edit each category and add a description, if you're implementing Info Boxes. If you're implementing this feature for tag archives (which is probably less common), then remember to do this for tags, as well.
