I haven’t tried this. I don’t think that CAF supports this. We’d probably have to implement some functionality to support this.
Not out of the box (accept for the prebuilt column preferences for SearchResults portlets). The common pattern is to store the user UI preferences as CSV strings and store as portlet preferences. You then use those preferences for your UI controls.
Hope this helps.
