An element that implements a FileThis user workflow as a set of panels that expand out to the right as things progress.
This is one of several variants of our FileThis Connect drop-in elements. This one expands to the right, when new UI elements are needed as the user traverses the workflow. Its use is appropriate when the hosting page can accomodate a significant increase in the horizontal space. If space on the page is more limited, or must be of fixed dimensions, another variant, like ft-connect-tabbed, or ft-connect-wizard would likely work better.
Initially, when a user account has no connections, this element will display a single panel of available websites. When the user selects one and enters their credentials, a connection is created and a second panel is created to the right of the first, displaying the new connection in a list. As the fetch operation proceeds for a connection and documents begin to be delivered, a third panel is created to the right of the second, displaying a list of document thumbnails.
