JPA ng-repeat filer - multiple id as one

I have joined two tables at this point. And it prints the code like this:

1
    7
1
    8
1
    9
2
2
3
4
5
5
6 

      

        
        
        
      

    

I am using angularjs ng-repeat to do something. My goal is to look like this:

1
    7
    8
    9
2
3
4
5
6 

      

        
        
        
      

    

My code:

<div id="menuList">
    <ul class="menuNav">
        <li class="menuList_Slide" ng-repeat="x in names">
            <div>               
                <a href="category.html?categoryid={{x.parentid}}" target="_self">{{x.parentid}}</a>
            </div>

            <div>
                <ul id="subCategories" ng-if="target == x.parentid">
                    <li>
                        <a href="category.html?subcategoryid={{x.id}}" target="_self">{{x.childid}}</a>
                    </li>
                </ul>
            </div>
        </li>
    </ul>
</div>

      

        
        
        
      

    

Can the ng-repeat filter be used to do what?
