I'm running WordPress 4.1 with the Twenty Fourteen Theme.
I've installed the "Post Tags and Categories for Pages" plugin, so I can assign Categories for my Pages.
I've set up a Categories menu via the standard widget.
(Appearance / Customize / Widgets / Primary Sidebar)
On the site, if I click on a given Category in the Categories menu, whole Pages are combined on to a single page.
How can I replace each whole Page with a short abstract, with a "Read More" link?
