hi, I could actually do the grayed out effect when the results are inside a fixed position div:
#ajaxsearchprores1_1{
box-shadow: 100vh 100vh 990px 100vh rgb(33 33 33 / 50%), -100vh 100vh 0 100vh rgb(33 33 33 / 50%);
}

the scrolling effect still needs coding though, but I will take care of fhat myself
