Accordion within another element is being cut down

Hey community,

I hope I will find here somebody who is kind to help me.

I am creating webiste for my job within x wordpress theme. And struggling to complete my vision... It is almost finished.. but in an odd way, where theme x support says its not anymore within the scope of their business.

So I have created column which I was happy with, but I wanted it to act as a slider. So I took slide element and copied the whole html code of the column to the slide element. And the accordion in the bottom of the slide, when opened, is being cut down by the bottom of the slide.
