Question

I am using AngularJS and trying to use ng-repeat or the like to take a multi-dimensional array and put it into the DOM as a mutli-level list.

From This:

    var menuOptions = [
        ["Page One"],
        ["Page Two"],
        ["Page Three"],
        ["Page Four", ["Sub-Page 1", "Sub-Page 2", "Sub-Page 3"] ],
        ["Page Five"]
    ];

To This:

   <ul>
        <li>Page One</li>
        <li>Page Two</li>
        <li>Page Three</li>
        <li>Page Four 
            <ul>
                <li>Sub-Page 1</li>
                <li>Sub-Page 2</li>
                <li>Sub-Page 3</li>
            </ul>
        </li>
        <li>Page Five</li>
   </ul>

I was unable to find anything in the Angular JS Documentation and a search of the web came to no avail. I am aware that I can handle something like this with plain ‘ol Javascript, or PHP but I would like to utilize some Angular JS thing like ng-repeat.

Any input is appreciated.

Thanks!

If you turn your array into the following

var menuOptions = [
    ["Page One", []],
    ["Page Two", []],
    ["Page Three", []],
    ["Page Four", ["Sub-Page 1", "Sub-Page 2", "Sub-Page 3"] ],
    ["Page Five", []]
];

You should be able to do this:

<ul>
  <li ng-repeat='option in menuOptions'>
    {{option[Ø]}}
    <ul>
      <li ng-repeat='suboption in option[1]'>{{suboption}}</li>
    </ul>
  <li>
</ul>
