Is there a way to set a container to fullscreen in the 'style' or 'class' parameters so that you can click on an icon and get it to open to full screen?

I am aware of the fullscreen function button:

<button id="fullscreen" onclick="$('#demoContainer').mb_fullscreen();">fullscreen</button>

but this appears to be only good for manipulating a container once it is already open, I would like to have 'fullscreen' already set so that when a user clicks on icon it opens to full screen, so something along the lines of:

<div class="containerPlus draggable resizable {fullscreen:'true', buttons:...

thank you
