Creating optional regions
You can use optional regions in your Adobe Dreamweaver Template to display certain contents of the input package only if certain conditions hold.
About this task
For example, assume that your input package contains an array of Components, some of which are news articles (based on a Schema called NewsArticle), while others are product descriptions (ProductDescription Schema). If you want to display these items differently or in different areas of the Web page, you can distinguish between them by setting a condition for each type of Component (for example, the region for news articles would have a condition "Schema must be NewsArticle"). If the condition you set never holds, the region remains empty.
You can, of course, also filter on any other condition. You can also combine conditions to create complex Boolean expressions.
