To create an External Link, begin by selecting Add Content > Create > New External Link. By default the new link will be placed into the _cascade > links folder. This can be moved later if the external link is to be shown in a left navigation menu.
There are only a few items that need to be filled in:
- Give the link a system name - like all system names, lowercase and no spaces.
- Fill in the display name - the type that will show in the left menu or quicklinks list.
- Enter the complete URL - everything including the http:// at the front.
Click the submit button and the link is created in the links folder. If you want this to be part of a left menu, now you can move it to the folder where it should be, and then reorder the list if needed.
