AngularJS - ng-repeat horizontally x number of times, then new line - angularjs

Question

I am trying to perform a simple ng-repeat on an <li>. In the past, i have created vertical ng-repeat. I am now trying to create a horizontal one, however, one that displays 4 items, then starts the ng-repeat again on a new line.
The way i have gone about this is using the grid-wrap technique (CSS) found here: http://builtbyboon.com/blog/proportional-grids
So each <li>, has a CSS class/width of one-quarter (25%).
Is this the correct/Angular way of going about it? Or should i be using some kind of $index on the <li> and triggering a <br> when $index == 3 ?
HTML:
<div ng-controller="MainCtrl">
<ul class="grid-wrap one-whole">
<li ng-repeat="product in Products" class="grid-col one-quarter">
<div class="product-container">
<div>{{ product.ModelNo }}</div>
<img ng-src="{{product.ImgURL}}" width="80%"/>
<div>${{ product.Price }}</div>
</div>
</li>
</ul>
</div>
CSS:
.grid-wrap {
margin-left: -3em;
/* the same as your gutter */
overflow: hidden;
clear: both;
}
.grid-col {
float: left;
padding-left: 3em;
/* this is your gutter between columns */
width: 100%;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
.one-quarter {
width: 25%;
}

Answer 1

I did some research and found this answer:
Customize ng-repeat in AngularJS for every nth element
<div class="section">
<div ng-repeat="items in MyList">
<img ng-click="AddPoint($index)" src={{items.image}} />
<span>{{items.currentPoint}}/{{items.endPoint}}</span>
<br ng-if="!(($index + 1) % 4)" />
</div>
So you could use this:
<br ng-if="!(($index + 1) % 4)" />
There doesn't seem to be a better way. You probably can't get around using index.
