I don't have AA at the the moment to check, but looking at the velocity template for checkboxes in the VFS, it does show that the checkbox control has a CaptionAlignment property (with possible choices of "right", "center", or "left"). So, if that property doesn't show in AA you should be able to set it via code. All that does basically is add CSS classes to set the alignment, whether or not there is CSS in place for those classes to actually set the alignment is another question, but you could add that CSS for the CSS classes added to the control yourself.
It does not allow you to specify which side of the checkbox the label appears on though if that is what you're asking. You could possibly change that for *all* checkbox controls if you want by modifying the velocity template in the VFS for Model/QuickForms/Web/QFCheckBox.WebControlRenderingTemplate.vm |
