Tabs closing effect

Hello everyone, i am working on some tabs using the very simple tabs.

Question, in the tabs panel, how can i get the tab to close when pressed ? (of course when it’s open).

So i want it to work this way:

  1. Press button
  2. Panel opens
  3. Press button
  4. Panel closes

Thanks alot for your help! Very much apprechiated!
