div show / hide horizontal

div show / hide horizontal

i used below source code for show / hide div, how to move horizontal.
demo link: http://papermashup.com/demos/jquery-show-hide-plugin/
(function ($) { $.fn.showHide = function (options) {
//default vars for the plugin
var defaults = {
speed: 1000,
easing: '',
changeText: 0,
showText: 'Show',
hideText: 'Hide'
};
var options = $.extend(defaults, options);
$(this).click(function () {
$('.toggleDiv').slideUp(options.speed, options.easing);
// this var stores which button you've clicked
var toggleClick = $(this);
// this reads the rel attribute of the button to determine which
div id to toggle
var toggleDiv = $(this).attr('rel');
// here we toggle show/hide the correct div at the right speed
and using which easing effect
$(toggleDiv).slideToggle(options.speed, options.easing, function() {
// this only fires once the animation is completed
if(options.changeText==1){
$(toggleDiv).is(":visible") ? toggleClick.text(options.hideText)
: toggleClick.text(options.showText);
}
});
return false;
});
};
})(jQuery);
