Add Dynamic Wrapper div to a Row
that's not much to go on, so I'll assume that the module generates one button per slide in the slideshow, and you want them centered underneath the image area ?

It's hard to know without the markup, but a couple of css selectors should do the trick.

for the containing div, if it has an id, or a uniquely addressable class, try something like this:

#container {
    width: 100%;
    text-align: center;
}


and if the button divs or whatever have no convenient id or class, address them something like this:

#container &gt; div {
    display: inline-block;
}


I think you may be better off sticking to css. Post the relevant rendered html, and perhaps we can help.
