It's native behavior of ExpandableListView so if any Item doesn't have children, implicitly won't be expanded but you need to set OnClickListener for both groups (Items) and children (Options):

    public boolean onChildClick(ExpandableListView parent, View row, 
                               int groupPosition, int childPosition, long id) {

       // callback method after click for Options
       return false;
    }


    public boolean onGroupClick(ExpandableListView parent, View row, 
                                 int groupPosition, long id) {

       /** if you are using BaseAdapter subclass implementation **/

       adapter.getGroup(groupPosition)).getChildren() == null) {
          // item doesn't have children
           return true;
       }
       else {
          // has children
           return false;
       }
