Your Web site is organized into channel groups and channels. While you create articles using the Article Manager, add photos using the Image Manager, etc., when it comes time to publish, you must first place your content on a channel.
Each channel group contains related channel pages. For example, you could create a channel group named “Opportunities” that contains the following channels:
To understand how channels fit into your Extend website, it might help to recall a typical Extend site organization.
Extend Website Organization:
A channel is like a section in a newspaper. When articles are published in newspapers, they are place in the sections related to the article, such as national, local, sports, business, or lifestyle. Similarly, articles in Extend are published on channels of related content.
Other than, perhaps, the navigation links on your pages...
your site users don't actually see channel groups and channels. They are just the devices used by Extend to organize your content. They will, however, see channel pages (see below).
You can quickly view all of the channels you have created by clicking Expand All at the top of the Channel Manager window. This will expand the channels and subchannels in all the groups you created. To close all of the channels, click Collapse All and only the group names display.
Channel are the primary pages that make up your website. These are the front pages for each section of your newspaper. There's not room for entire articles, so you post part of the article and link it to a "content page". Content pages only exist to hold entire individual pieces of content like articles.
