Avia Layout Builder, Modification, Module overlay another

Hi, I couldn’t find a topic on this, so I started a new one.

I am using a Layer Slider, which is working well.
I am then using a Shortcode for a search Widget just below it, also works great.

I wanted to create the AirBnb.com effect, where the search Shortcode is overlaying the background images.

I know it would be a z value change. and i’m comfortable doing this.

But, I was going to create another CONTENT ELEMENT, with position settings.

Do you have any wisdom, suggestions, or thoughts about doing that easier? before I start coding?

if not, can you point me to the files that I’ll have to adjust, or copy and change slightly to do what I want?
