I have one problem with angular ng-repeat and bootstrap. I tried divide view on two parts left image, right description, but next line oposite, left description and right image. I would like something like picture below
<div class="container">
<div class="row">
<div ng-repeat="item in items">
<div class="col-xs-6">
<img src="{{item.image}}" alt="#"/>
</div>
<div class="col-xs-6">
<div class="description">
<p>{{item.description}}</p>
</div>
</div>
</div>
</div>
</div>

Answer 1

You can check for odd or even iteration in the repeat loop and apply your class with either float left or right respectively.
<div class="container">
<div class="row">
<div ng-repeat="item in items" ng-class-odd="'img-left'">
<div class="col-xs-6 img-holder">
<img src=".." alt="#"/>
</div>
<div class="col-xs-6 text-holder">
<div class="description">
<p>........</p>
</div>
</div>
</div>
</div>
</div>
CSS
.img-left .img-holder{
float:left;
}
.img-left .text-holder{
float:right;
}
you can handle even condition directly in CSS or like above.

Answer 2

This is my solution. Using ng-class we check if the current index ($index) divided by 2 is zero then we add the float classes either .left or .right.
JSFiddle Demo
<div ng-controller='MyController'>
<div ng-repeat="val in arr">
<div class="row clearfix">
<div class="col-xs-6" ng-class="$index % 2 === 0 ? 'left':'right'">
{{val}}
</div>
<div class="col-xs-6" ng-class="$index % 2 === 0 ? 'right':'left'">
<img src="http://lorempixel.com/400/200/" alt="">
</div>
</div>
