Try this
$(this).html(value).css('opacity', 0)
.slideDown('slow')
.animate(
{ opacity: 1 },
{ queue: false, duration: 'slow' }
);
Question
Is it possible to have a slight fade to the .slideUp & .slideDown so it slides upwards with a fade?
options.trickerPanel.slideUp(function() {
$(this).html(value).slideDown();
Here is the full code for example http://jsfiddle.net/LtpHv/1/
Solution 2
Try this
$(this).html(value).css('opacity', 0)
.slideDown('slow')
.animate(
{ opacity: 1 },
{ queue: false, duration: 'slow' }
);
OTHER TIPS
Whats wrong with a simple sequential fade + slide?
$('#a').fadeOut();
$('#a').slideUp();
Both actions will take place at the same time giving you a nice fade + slide effect.
Try adding a number in the SlideDown function, this is the time in milliseconds that it takes for the animation to take place.
slideDown("Enter number here")
slideUp("Enter number here", function(){ }
