Playlist popup/lightbox window
Design and Skin Customization
If the info from that link doesn't work...
The modal is positioned relative to the button using javascript.
It would be easiest to move your button to the right.
If you can't do that you could try changing the function jrPlaylist_position in /modules/jrPlaylist/js/jrPlaylist.js
/**
* position the playlist on the page via javascript so it doesnt get hidden
* by the overflow hidden on the .row class.
*/
function jrPlaylist_position(module, item_id){
var bid = $('#playlist_button_' + module + '_' + item_id);
var bpr = $(window).width() - bid.offset().left;
var bpt = bid.offset().top;
$('#playlist_' + module + '_' + item_id).appendTo('body').css({'position': 'absolute', 'right': (bpr - 35) + 'px', 'top': (bpt + 35) + 'px'});
}
