title: How to hide child items for a particular group in ExpandableListView?
body: <p>My <code>ExpandableListView</code> has always single children for a particular group. For some groups I'd like to hide child items however I'd like the group to be still clickable (every group item after click changes it's layout). So what should be returned for such groups from <code>getChildView</code>?</p>
