How can I build a multi-column layout with a Knockout foreach?

Question

I've included a code snippet which demonstrates the problem I'm trying to solve. I'm trying to build a two column layout based upon the data within an observableArray . I've tried using the Knockout if bindings, but that doesn't work well within the foreach . This seems like it should be very simple, but for some reason I haven't been able to figure out how to make this work within the realm of Knockout.

 function ViewModel() { var self = this; self.People = ko.observableArray([1, 2, 3, 4, 5]); } var viewModel = new ViewModel(); ko.applyBindings(viewModel);

Answer 1

Try that:

<div class="row">
    <div class="col-xs-12" data-bind="foreach: People">
        <!-- ko if: $index() % 2 == 0 -->
        <div class="row">
            <div class="col-xs-6" data-bind="text: $parent.People()[$index()]"></div>
            <div class="col-xs-6" data-bind="text: $parent.People()[$index()+1]"></div>
        </div>
        <!-- /ko -->
    </div>
</div>
