Add class to section in tpl In my template (Bootstrap), in the following line:

&lt;section&lt;?php print $content_column_class; ?&gt;&gt;


I need to add a custom class AND keep the dynamic column class.
I tried &lt;section class="myclass &lt;?php print $content_column_class; ?&gt;"&gt; but it give me:

&lt;section class=" class=" myclass"="" col-sm-12"=""&gt;


Any idea what to do?
Try 

&lt;?php print $content_column_class; ?&gt; 


and see what is exactly printed

I think you should try something like this instead

&lt;section class="&lt;?php print "myclass ".$content_column_class; ?&gt;"&gt;


Hope This helps
Cheers
