let flowLayout = UICollectionViewFlowLayout().then {
    $0.minimumLineSpacing = 8
    $0.scrollDirection = .horizontal
}

lazy var collectionView: UICollectionView = {
    let collectionView = UICollectionView(frame: CGRect(x: 0, y: 64, width: recommendCellWidth, height: communityDiscussionCellHeight - 64), collectionViewLayout: flowLayout)
    collectionView.backgroundColor = .clear
    collectionView.showsHorizontalScrollIndicator = false
    collectionView.contentInset = UIEdgeInsets(top: 0, left: 20, bottom: 20, right: 20)
    collectionView.dataSource = self
