About UICollectionViewCompositionalLayout

[crazypoo]

Hello,I have a question.Just I use UICollectionViewCompositionalLayout,in which there are multiple items in group.How can I use this kit to slide to edit the whole group instead of a single cell?
Here is my layout code:
func layoutConfig()-> UICollectionViewCompositionalLayoutConfiguration
{
let config = UICollectionViewCompositionalLayoutConfiguration()
config.interSectionSpacing = 30
return config
}

func comboLayout()->UICollectionViewCompositionalLayout
{
    let layout = UICollectionViewCompositionalLayout.init { section, environment in
        return self.generateSection(section: section)
    }
    layout.register(DODecorationView.self, forDecorationViewOfKind: "background")
    return layout
}

func generateSection(section:NSInteger)->NSCollectionLayoutSection
{
    let sectionModel = self.listModel[section]

    var group : NSCollectionLayoutGroup
    var behavior : UICollectionLayoutSectionOrthogonalScrollingBehavior = .continuous

    var bannerItemSize = NSCollectionLayoutSize.init(widthDimension: NSCollectionLayoutDimension.fractionalWidth(1), heightDimension: NSCollectionLayoutDimension.fractionalHeight(1))
    var bannerItem = NSCollectionLayoutItem.init(layoutSize: bannerItemSize)
    
    var bannerGroupSize : NSCollectionLayoutSize
    
    bannerItem.contentInsets = NSDirectionalEdgeInsets.init(top: 0, leading: 0, bottom: 0, trailing: 0)
    bannerGroupSize = NSCollectionLayoutSize.init(widthDimension: NSCollectionLayoutDimension.absolute(kScreenWidth-20), heightDimension: NSCollectionLayoutDimension.absolute(450))
    group = NSCollectionLayoutGroup.custom(layoutSize: bannerGroupSize, itemProvider: { layoutEnvironment in
        
        var customers = [NSCollectionLayoutGroupCustomItem]()
        let itemHeader = NSCollectionLayoutGroupCustomItem.init(frame: CGRect.init(x: 0, y: 0, width: kScreenWidth-20, height: 100), zIndex: 1001)
        customers.append(itemHeader)
        
        let itemScrol = NSCollectionLayoutGroupCustomItem.init(frame: CGRect.init(x: 0, y: 100, width: kScreenWidth-100-20, height: 200), zIndex: 1002)
        customers.append(itemScrol)

        let itemInfo = NSCollectionLayoutGroupCustomItem.init(frame: CGRect.init(x: kScreenWidth-100-20, y: 100, width: 100, height: 200), zIndex: 1003)
        customers.append(itemInfo)

        let itemFooter = NSCollectionLayoutGroupCustomItem.init(frame: CGRect.init(x: 0, y: 300, width: kScreenWidth-20, height: 150), zIndex: 1004)
        customers.append(itemFooter)
        
        return customers
    })


    var sectionInsets = NSDirectionalEdgeInsets.init(top: 10, leading: 10, bottom: 10, trailing: 10)
    var laySection = NSCollectionLayoutSection(group: group)
    laySection.orthogonalScrollingBehavior = behavior
    laySection.contentInsets = sectionInsets

    return laySection
}
