How to combine slick slider with slide-attached windows and check slide for visibility?

Question

css

There is a need to make a slider, when you click on the slide of which the block attached to this slide opens with an absolute. However, overflow clips it. Is there a way to get out?

And how can you check the visibility of a slide? I did a check through slick-active, but when rewinding the slider, it is reset and hung up again.
