I want to move Slider from header to content, in top of the posts. That because I have non very wide images to post and the pase seemt unbalanced. I think if I move the slider in Content, as I said, having in the left side the widgets column, the page will have a nice balanced design.
We have designed our theme in this way. Recently its not possible. If you want then you need to have custom coding for it. But while updating our new version all your custom code will be lost. So we recommened not to change the code.
