❔ Panel scroll bar only vertical

private void InitializeAndAddPanel()
{
    panel.FlowDirection = FlowDirection.TopDown;
    panel.Anchor = AnchorStyles.Left | AnchorStyles.Right;
    panel.Dock = DockStyle.Fill;
    panel.AutoSize = false;
    panel.AutoScroll = true;
    Controls.Add(panel);
}
private void AdjustFormAndPanelContentsSize()
{
    SetWidthForAllControls(panel.Controls);
    panel.Height = Math.Min(MaxHeight, accumulatedControlsHeight);
    Height = Math.Min(MaxHeight, accumulatedControlsHeight);
    Width = Math.Max(Width, maxControlWidth);
}

I call the first method first and then the 2nd method in the init method
