如何在shinydashboard中显示默认显示的侧边栏菜单项

Question

在侧边栏栏下，我创建了一个菜单，如下图所示，它会显示菜单上的单选按钮。

        sidebarMenu(
                     menuItem("Data Upload",tabName = "DataUpload", icon = icon("upload"),
                               radioButtons("radio", label = "Select input format",
                                            choices = list("Excel(xls/xlsx)" = 1, "CSV" = 2, "sql" = 3),selected = 1)
                                ))

但是我需要在默认情况下显示它并单击菜单它应该隐藏放射线。
