问题
It's my very first question here and i hope you can help me. I'm trying to set up a product-overview page with the bootstrap grid. I have got 4 products in a row for large screen sizes. For smaller screen sizes i'd like to have 2 products per row.
The trick is, i want to have the product details in a collapsed container between the rows, that opens up, when i click on a product. It's working for the large screen sizes with 4 products. But how to achieve that the collapsed container is showing up right after the row, where i clicked my product, independent of how many products i have got per row. On smaller sizes the collapsed container opens after the second row, even if i click a product in the first row.
When i place every collapsed container right behind the product in the markup it pushes away the other products when i open it up.
Sorry, it's a bit complicated, i hope you know what i mean.
For better understanding have a look on my pen on codepen.
I want to keep it as simple as possible and I'm not sure which way to go?

A while back, I answered a similar question here: Bootstrap responsive grid layout (3 columns) with collapsed/hidden col-12 beneath each grid element
Basically you have to put the collapsed rows below the appropriate col-* to fit your smallest layout. So in your case:
<div class="row">
<div class="col-md-3 col-xs-6">
<a href="#one" data-toggle="collapse"><img src="//placehold.it/600"></a>
</div>
<div class="col-md-3 col-xs-6">
<a href="#two" data-toggle="collapse"><img src="//placehold.it/600"></a>
</div>
<div class="col-xs-12 overlay collapse" id="one">
1
</div>
<div class="col-xs-12 overlay collapse" id="two">
2
</div>
<div class="col-md-3 col-xs-6">
<a href="#three" data-toggle="collapse"><img src="//placehold.it/600"></a>
</div>
<div class="col-md-3 col-xs-6">
<a href="#four" data-toggle="collapse"><img src="//placehold.it/600"></a>
</div>
<div class="col-xs-12 overlay collapse" id="three">
3
</div>
<div class="col-xs-12 overlay collapse" id="four">
4
</div>
</div>
And then you'd need some extra CSS to overlay the collapse column so that it's full width under the entire row on larger screens.

For Bootstrap 4, this scenario is easier because of flexbox ordering..
