Swing method to show or hide part of a panel on button click?

Question

I'd like to be able to show and hide (and therefore grow and shrink the jpanel as appropriate) in my swing application. I've seen something similar on websites that I imagine uses JS and JQuery.

What I'm after is the ability to click a button (that might say 'Advanced options') that then 'slowly' grows the panel and reveals (setVisible(true)) components.

Is this possible using Swing? I've tried looking round the web, and SO but I only seem to get JQuery questions, or unhelpful Java posts. This is the closest I've found.

@user3313050: no, that would be unnecessarily complicated as you'd have to be sure that all Swing code is called on the EDT. Simplest is to use a Swing Timer for your animation. — Hovercraft Full Of Eels, Apr 01 '14 at 16:50

Use a Swing Timer to animate your slide. For example, this link has code that places the components in a JLayeredPane and slides one component over the other, again using a Swing Timer: slide effect with JPanel.

Another useful effect is to fade out from one JPanel to another. For an example of this that uses a Swing Timer as well as a CardLayout, please check out this answer.
