This feature allows you to put another site within your site. You
can also use it to put two parts of your own site together. If
you want to have a window that will scroll through one window while
keeping your other window open you have found the feature you were
looking for.
1. From the Add Block Menu on the Edit Column/Header/Footer bar, choose Add Feature.
2. Choose Include URL.
3. Type in the website URL of the site you would like included in your website.
4. Decide how you would like the URL to appear on your page. An
iframe is an inline frame that contains another document. Not checking
the iframe box will simply add the page referred to by your URL to your
webpage. Checking the box will create your URL within an iframe, which
can be navigated within the site.
