Get props in List of List of Object based on Specific Index in Sightly

Hello All,

I have a list which I call rows here, then inside that I have another list which is list itself, but I want to get specific index of that list based on outer list index.(rowsList.index), after that I will get the objects inside inner list to show props.

But it is not going inside   <sly data-sly-list.singleList="${logic.listOLists[rowsList.index]}">

I have these two list in my service:

public ArrayList<ArrayList<List<MyObject>>> listOfLists = new ArrayList<ArrayList<List<MyObject>>>();
public ArrayList<List<MyObject>> singleList = new ArrayList<List<MyObject>>();

each item of singleList is like this:

public List<MyObject> myObject = new ArrayList<>();

How should I get inside that listOfLists based on index of outter list?

What is exactly method I need to make sure it will get name/label/required from myobject?

I know that service is adding correctly to the "listOfLists" and "singleList".

Here is part of my sightly.

<div data-sly-use.logic="xx.xx.model.searchRows">

<table>

     <sly data-sly-list.rows="${logic.selectedRows}">

          <tr>

               <td>

                    <input type="text" id="name" name="name" value=${rows.name}>

               </td>

               <td>

                     <sly data-sly-list.singleList="${logic.listOfLists[rowsList.index]}">

                            <sly data-sly-list.innerList="${singleList.listChildren}">

                                 <h2>${innerList.name} - ${innerList.label} - ${innerList.href}</h2>

                           </sly>

                    </sly>

             </td>

         </tr>

   </sly>

</table>

</div>

Thanks for your time.
