I work with the UIKit framework. When editing the content in J5, JCE deletes the uk-grid attribute from the DIV element (see code). When I edit the whole thing via code mirror uk-grid is not deleted. How can I solve this problem in the JCE editor?
example:
//original
<div uk-grid>
<div></div>
<div></div>
</div>
//after editing with JCE
<div>
<div></div>
<div></div>
</div>
