Hi Thi Han,

Thank you for contacting us.

In the Application menu, the size of the second-level popup should be the same as the size of the second column. However, you can alter this behavior by handling the DropDownOpening event of your first-level menu items. The following sample demonstrates this:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        foreach (RadMenuItem menuItem in this.radApplicationMenu1.Items)
        {
            menuItem.DropDownOpening += new CancelEventHandler(menuItem_DropDownOpening);
        }
    }

    void menuItem_DropDownOpening(object sender, CancelEventArgs e)
    {
        RadMenuItemBase menuItem = sender as RadMenuItemBase;
        if (menuItem != null)
        {
            RadPopupOpeningEventArgs eventArgs = (RadPopupOpeningEventArgs)e;
            eventArgs.CustomLocation = new System.Drawing.Point(eventArgs.CustomLocation.X,
                menuItem.ControlBoundingRectangle.Y + this.radApplicationMenu1.DropDownButtonElement.DropDownMenu.Location.Y);

            menuItem.DropDown.MinimumSize = Size.Empty;
        }
    }
}

I hope this will help you. Feel free to ask if you have any additional questions.
