How to set max-height to div with position: absolute?

Question

css

Good afternoon.
There is an absolutely positioned DIV (this is important) that contains a JS accordion that can be insanely tall when expanded. It is necessary to set the diva to the maximum height = screen height, so that when the chord is expanded, the entire sheet does not go down the page.
So, max-height : 100% in absolute does not shoot, but it is very necessary.

Answer 1

var height = $(window).height();
$(".accrodion").css("height", height);

Answer 2

As an option, file a function that checks the screen height, put it in resize and add this value to max-height.
