I found this conflict between the bootstrap scripts and the yii framework. When adding a template and scripts to yii:
<script src="<?php echo Yii::app()->request->baseUrl; ?>/js/bootstrap.min.js"></script> a file appears in the DOM:
<script src="/assets/25b4e139/gridview/jquery.yiigridview.js" type="text/javascript"> which only works after removing the bootstrap.min.js . Tell me, who knows how to deal with it?
