Show hide a region clicking on a botton

Hi, I need to show/hide a region cliking on a botton.
I’ve tried with an animated region but I can’t do it.
Can anubody help me?

Hi Andrea,

Thank you so much. It works perfectly, of course.

Maybe you teach me another very important topic. How to use variable and ‘set value’ option. In particular I find this option in server connect condition step. Thank you very much indeed.

Hi Andrea,
The setvalue step in server connect is used as a variable where you set a value (any value you need) - for example results of a query, or any other value.
When you enable the “output” option for the setvalue step it becomes available in the data picker on your page, so you can use it in expressions there.
