here is the code that you have to add so you can have a limit of items displayed and the content scrollable

add this property:
public var maxVisibleItems: Int = 5 {
didSet {
self.setNeedsUpdateConstraints()
}
}

edit tableHeight and updateConstraints:

fileprivate var tableHeight: CGFloat {
let visibleItemsCount = min(dataSource.count, maxVisibleItems)
return tableView.rowHeight * CGFloat(visibleItemsCount)
}

public override func updateConstraints() {
if !didSetupConstraints {
setupConstraints()
}

didSetupConstraints = true

let layout = computeLayout()

if !layout.canBeDisplayed {
    super.updateConstraints()
    hide()

    return
}

xConstraint.constant = layout.x
yConstraint.constant = layout.y
widthConstraint.constant = layout.width
heightConstraint.constant = layout.visibleHeight

tableView.isScrollEnabled = layout.offscreenHeight > 0 || dataSource.count > maxVisibleItems

DispatchQueue.main.async { [weak self] in
    self?.tableView.flashScrollIndicators()
}

super.updateConstraints()

}
