Shinydashboard:是否不可能有嵌套的菜单子项？无法使其发挥作用

Question

我正在使用shinydashboard,并且需要构建两级嵌套子菜单.我正在尝试这个并且不会起作用:

library(shinydashboard)
sidebar <- dashboardSidebar(
  sidebarMenu(id = 'sidebarmenu',
              menuItem('x', tabName = 'x', icon = icon('line-chart')),
              menuItem('y', tabName = 'y',
                       icon = icon('line-chart'),
                       menuSubItem('a',
                                   tabName = 'a',
                                   icon = icon('line-chart')),
                       menuSubItem('b',
                                   tabName = 'b',
                                   icon = icon('line-chart'),
                                   menuSubItem('l',
                                               tabName = 'l',
                                               icon = icon('line-chart')),
                                   menuSubItem('m',
                                               tabName = 'm',
                                               icon = icon('line-chart'))),
                       menuSubItem('c',
                                   tabName = 'c',
                                   icon = icon('line-chart'))
              )))

给我错误:

Error in menuSubItem("b", tabName = "b", icon = icon("line-chart"), menuSubItem("l",  : 
  Can't specify both href and tabName

是否有可能建立两级嵌套？当然,上面的删除l和m子菜单工作得很好(有一级子菜单).

如果您只使用menuSubItem最低级别,则调用其他级别menuItem.这会对你的目的有用吗？

sidebar <- dashboardSidebar(
sidebarMenu(id = 'sidebarmenu',
            menuItem('x', tabName = 'x', icon = icon('line-chart')),
            menuItem('y', tabName = 'y',
                     icon = icon('line-chart'),
                     menuItem('a',
                                 tabName = 'a',
                                 icon = icon('line-chart')),
                     menuItem('b',
                                 tabName = 'b',
                                 icon = icon('line-chart'),
                                 menuSubItem('l',
                                             tabName = 'l',
                                             icon = icon('line-chart')),
                                 menuSubItem('m',
                                             tabName = 'm',
                                             icon = icon('line-chart'))),
                     menuItem('c',
                                 tabName = 'c',
                                 icon = icon('line-chart'))
            )))
