Umbraco C# - Display 2 different columns on foreach loop (1-2) (1-2)

Question

I'm trying to display data from the Umbraco in this order 1-2 in foreach loop (bootstarp columns), but my code is displaying in this order of columns 1-1, instead of 1-2 on loop. It does not add the second column to the second row just one column.

E.g. 1 item, then 2 items, then 1 item again with different columns displays.

whats the better approach to make 1-2 on loop of content? I'm kinda lost on this one. Any help would be good.

   @foreach(var data in Model.Content.Children().Where(x => !x.GetPropertyValue<bool>("umbracoNaviHide"))){

        if(data.HasValue("blogNested")){

           var items = data.GetPropertyValue<IEnumerable<IPublishedContent>>("blogNested");

           int i = 0 ;

Answer 1

It could be something like this

var items = data.GetPropertyValue<IEnumerable<IPublishedContent>>("blogNested")
    .ToList();

while (items.Any())
{
    var oneItem = items.First();
    items.Remove(oneItem);

    <div class="row">
        <div class="col-md-12">
            @oneItem.Id
        </div>
    </div>

    var twoItems = items.Take(2).ToList();

    if (twoItems.Any())
    {
        <div class="row">
            @foreach (var item in twoItems)
            {
                items.Remove(item);
                <div class="md-6">
                    @item.Id
                </div>
            }
        </div>
    }
}

This will render

<div class="row">
    <div class="col-md-12">
        <text>{{Id}}</text>
    </div>
</div>
<div class="row">
    <div class="md-6">
        <text>{{Id}}</text>
     </div>
     <div class="md-6">
          <text>{{Id}}</text>
     </div>
</div>
<div class="row">
    <div class="col-md-12">
        <text>{{Id}}</text>
    </div>
</div>
...
