Hi how are you? 
I want to have four different portfolio pages, each of this pages are like "Flats" "Buildings" "Planning" and "Skyscraper" 
https://prnt.sc/l4g583
Then when I click on "Flats" for example this portfolio layout shows 
https://prnt.sc/l4g7ja  which is great but when I add a new portfolio item it shows on all portfolio pages. 
I read on other discussions similar needs of different people but I don´t understand them! 
I also tried to copy this shortcode on a blank page:
[portfolio count="6" style="grid" columns="3" category="Flats" category_multi="" orderby="date" order="DESC" exclude_id="" related="0" filters="0" pagination="0" load_more="0" greyscale="0"]
I don´t like the result 
https://prnt.sc/l4g99f but I think It´s possible to style it with custom css. I tried this for example:
.portfolio_group .portfolio-item .desc {
                        display:none;
}
Thanks in advance!!

All I can change with CSS is hiding titles and strings.
If you want to change the style of layout in the shortcode, just change the line style="grid" to something else, like style="flat" - which is most similar to what you want to achieve.
