I am trying to build a scrollable screen which contains multiple lists. To achieve that I am doing something like this:

LazyColumn{
     item{
     }
     items(list of items){
       ...
     }
     item{
     }
     items(list of items){
       ...
     }
     ...
}

My problems is that I would like to set a background to each list, but I can't set a modifier to the "items(list){}" object. How can I build this screen? Should I approach the whole screen build in a different way?

Each item in LazyColumn is an individual view, there is no parent view of the items within the same block: they are simply grouped by data.

You can apply the same background to every element in items, if you apply it before any paddings, it will look as you expect:

LazyColumn {
    item {
        Text("title 1")
    }
    items(10) {
        Row(Modifier.fillMaxWidth().background(Color.Blue)) {
            Text("hello $it")
        }
    }
    item {
        Text("title 2")
    }
    items(10) {
        Row(Modifier.fillMaxWidth().background(Color.Green)) {
            Text("hello $it")
        }
    }
}

Result:
