Currently i have an Android app with 3 level data grouping being displayed on two panes. Left pane contains the high level data, right pane contains an expandable list view (aka an accordion) that combines the next two levels.
Users of my app don't really care about the actual group name itself in most of the cases, only about getting to one specific item (no multiple selection). At the same time i want to keep the exploration aspect by having those group names there in a some way.
I've reviewed the tab approach as in the Google Play app but that seems to be a too lengthy journey (Searching through horizontally scroll-able categories) to get to a specific item on devices smaller then a large tablet. .
I am currently inclined on having a "Filter as you type" in the ActionBar to narrow down the results.
Here is a mock to demonstrate what i currently have
Any thoughts on possible alternatives?
