We are having a discussion about faceted navigation. The main question is: Should one of the filters be "ALL" or does an ALL filter create unnecessary interaction and confusion?
Version 1 presents the default view and version 1B shows what happens when the user clicks to filter only Apples. Question 1. Do we need to have the ALL filter? If it presents a better experience, would the filtering behave this way?
Version 2 shows no ALL filter. By default all filters are selected and a maximum number of results are shown. Only by clicking a filter, do the results narrow.
Which ones works better and why? Is it because of the number of perceived steps? Redundancy?
Are there any documents on best practices around the ALL or no ALL filter? Thanks,
