【问题描述】：
我一直在寻找解决方案，但我没有找到它
我的问题是我的仪表板看起来像这样：
即使我没有选择它们，它也会选择所有选项卡（如预渲染）
我尝试用一个按钮创建一个 observeEvent，但它不知道如何在他们点击后显示 UI。
我的代码是
library(shiny)
library(shinydashboard)
gamestop <- tags$img(src = "GSLL.png",
height = '30', width = '170')
ui <- dashboardPage(skin = "yellow",
dashboardHeader(title = gamestop,
dropdownMenu(type = "tasks",
messageItem(
from = "My contact",
message = "x",
icon = icon("glyphicon glyphicon-envelope"),
href = "mailto:x"),
messageItem(
from = "Leads",
message = "y",
icon = icon("glyphicon glyphicon-envelope"),
href = "mailto:y"),
messageItem(
from = "",
message = "z",
icon = icon("glyphicon glyphicon-envelope"),
href = "mailto:z"),
icon = icon("envelope")
)
),
dashboardSidebar(
sidebarMenu(
menuItem("Main menu", tabName = "main_menu", icon = icon("home")),
menuItem("Peripherals", tabName = "peripherals", icon = icon("hdd")),
menuItem("Database repair", tabName = "widgets", icon = icon("th")),
menuItem("Polling", tabName = "polling", icon = icon("cloud")),
menuItem("more issues!!", tabName = "issues", icon = icon("ad"))
)
),
dashboardBody(tags$head(
tags$link(rel = "stylesheet", type = "text/css", href = "Custom.css")),
fluidPage(
tabItem(tabName = "peripherals",
h1("Peripherals",
style = "color:#15942B"),
tabsetPanel(type = "tabs",
tabPanel("Printers",br(),
tabsetPanel(type = "tabs",
tabPanel("M452DW",br(),
tabsetPanel(type = "tabs",
tabPanel("Not pinging"),
tabPanel("Error messages")
)
),
tabPanel("M402DW",br(),
tabsetPanel(type = "tabs",
tabPanel("Not pinging")
),
)
)
),
tabPanel("Pinpad",br(),
tabsetPanel(type = "tabs",
tabPanel("Offline / busy"),
tabPanel("Not turning on")
)
),
tabPanel("Scanners",br(),
tabsetPanel(type = "tabs",
tabPanel("GBT4400"),
tabPanel("DS2278")
)
),
tabPanel("Receipt printer / cashdrawer",br(),
tabsetPanel(type = "tabs",
tabPanel("Receipt printer"),
tabPanel("Cash drawer")
)
),
tabPanel("Label printer",br(),
tabsetPanel(type ="tabs",
tabPanel("ZD410"),
tabPanel("LP2824 & +")
),
)
)
), #Final tab peripherals
tabItem(tabName = "main_menu",
h1("Main menu",
style = "color:#15942B"),
strong("Here we can add the news of the day or a welcome image"),br(),
br(),
br(),
strong("This is a work in progress, to be presented to our team leads so we can make
it an aid page for all of us")
),
tabItem(tabName = "issues",
h1("More issue resolutions to come!!!!!",
style = "color:#15942B" ),
strong("My plan is to add the hardest issue resolutions for our team, so they can access this web page and
with a glipse they can resolve the issue in hand")
),
tabItem(tabName = "polling",
)
)
)
)
)
server <- function(input, output) {
observeEvent(input$tabs,
if(input$sidebarmenu == "Printers"){
})
}
shinyApp(ui, server)
我想知道当用户点击标签本身而不是之前如何呈现标签
非常感谢！！！

我在您的代码中添加了第二个选项卡面板和选项卡面板，但问题仍然存在 - 当我单击第一个选项卡时，所有选项卡都被呈现或“激活”
