I've got a set of Miller Columns on a web application that could be wider than the page width. So this means the first level of the hierarchy might not be visible anymore. What's the most effective way for users to navigate "back" in a set of Miller Columns?
Some ideas might include:
- Horizontal scroll bar
- A "back" button in the upper right corner somewhere
- A "back" item as the last/first item in each list
An example of all of these in action:
(Note: my data is actually a set of reports, but I thought this would be a better example)
Or, maybe it would work well enough to autoscroll the columns so the one in focus is always in the center? Or something else?
