title: What sets column width / distribution in Yii2's DetailView?
body: <p>The same view, the same <code>DetailView</code>, the same code, different model, different end result:</p>

  <p>What sets column width in this case? Why it is shifting with each record? Is this a Bootstrap or Yii2 issue? I tried to analyse generated code with Chrome Dev Tools, but got no conclusions. As you can see, there is a lot of empty spaces in both columns, so column width shifting should not occur.</p>
  
  <p>Most important -- how to prevent that? How to make sure, that every view will look exactly the same, no matter what data will be printed inside <code>DetailView</code>?</p>
