I was not sure where the best topic is to post this message so I decided to post under bug reports.
When rendering checkBoxList CHtml uses a template "{input} {label}". This results in a form line like
<input id="info0" value="1" type="checkbox" name="info[]" /> <label for="info0">ITEMLABEL</label>
But label tag writes the label text to a new line after checkbox. So items are displayed like:
X
ITEMLABEL
X
ITEMLABEL
Its probably possible to fix this by css but in order to have a correct view in basic html layout, CHtml can be changed like following (CHtml lines 857-859):
Current Version:
$option=self::checkBox($name,$checked,$htmlOptions);
$label=self::label($label,$htmlOptions['id'],$labelOptions);
$items[]=strtr($template,array('{input}'=>$option,'{label}'=>$label));
Version that renders label text and checkbox in label tag.
$option=self::checkBox($name,$checked,$htmlOptions);
$template=self::label($template,$htmlOptions['id'],$labelOptions);
$items[]=strtr($template,array('{input}'=>$option,'{label}'=>$label));
I always make this change after installing a new version of yii and I hope this change can be applied to upcoming versions.
