In the examples <template> tags have wrong highlight color, should be blue not red

The following should be groups[groupIndex] instead of groups[index]
// user group data corresponding to groups[index]

{
  index: 0,           // data index for this item
  groupIndex: 0,      // group index for this item
  groupItemIndex: 0,  // index within group for this item
  selected: false,    // selection state for this item
  model: {            // user data corresponding to data[index]
    /* user item data  */
  },
  groupModel: {       // user group data corresponding to groups[index]
    /* user group data */
  }
}

For me its completely unclear what the difference is between groupIndex and groupItemIndex

2. not clear the difference between class="row" class="item"

3. divider attribute and class?
   <div divider class="divider">{{groupModel.letter}}</div>

4. Highlight that the default height is 200 of a item and should be changed
