## Customizing your view of Discussion categories and topics

When you click `Discussion` in the menubar, you will see a list. Under each category, you'll see any topics and replies that have been added. To view the categories and all the topics and replies, click `Expand All`. To view just the categories, click `Collapse All`.

If a topic has replies, click the small paper stack icon to expand the view so that a top-level item and all the replies below it are visible.

#### Layout options

The Discussion tool uses two frames to display discussion topics and replies.

To change your layout, follow the instructions below:

1. To change the display to a two-column vertical layout, select `Column Layout` from the "View:" drop-down list. In this layout, the left frame shows the hierarchy of categories, topics, and replies. Clicking a topic or reply shows the content of the message in the right frame.
2. To change to a two-row horizontal layout, select `Row Layout` from the "View:" drop-down list. In the this layout, the top frame shows the hierarchy of categories, topics, and replies; the content appears in the bottom frame.
