How do I add a Label Hint to Kartik DetailView
<p>I'm using Kartik DetailView and would like to have a hint appear when the user hovers over the label (like the GII forms).  I've tried the following, but it does not work.</p>

<pre><code> $attributes = [
    [   'attribute'=&gt;'name',
        'inputWidth'=&gt;'50%',
    ],
    [   'attribute'=&gt;'round_precision',
        'hint' =&gt; 'Specify the number of decimal digits after the decimal to round to.  Use a negative value to round the integer part of the number to the number of digits before the decimal. A value of 1 will round 1.855 to 1.7, and a value of -2 will round 1.855 1.86.  A value of -1 will round 17.6 to 18, and a value of -2 will round 17.6 to 20.',
        'inputWidth'=&gt;'10%',
    ],
];
</code></pre>

<p>How do I get Gii-like hints in the Kartik DetailView Widget?</p>
