R 闪亮的仪表板，仅当选择特定侧边栏菜单项中的特定选项卡面板时才显示条件面板

Question

下面我提供了我正在尝试创建的闪亮仪表板的框架。我已经为此奋斗了很长一段时间，但不知道如何让它发挥作用。

应用程序当前行为： 现在，选择菜单项 1 侧边栏项目时，“选择日期范围”日期输入可见。

期望的行为：我希望“选择日期范围”输入仅在同时选择“菜单项 1”和“选项卡 1”时才可见。

library(shiny)
library(shinydashboard)
library(shinyWidgets)
library(lubridate)

generate_dates <- function(start_date, end_date) {
  all_dates <- seq(start_date, end_date, by = "days")
  all_mondays <- all_dates[weekdays(all_dates) == "Monday"]
  return(all_mondays)
}

start_date <- floor_date(as.Date("2023-07-01"), unit = "week", week_start = 1)
end_date <- floor_date(as.Date("2023-12-06"), unit = "week", week_start = 1)
dates <- generate_dates(start_date, end_date)

df <- data.frame(
  Week = dates,
  Value_1 = sample(c("A", "B", "C", "D"), length(dates), replace = TRUE),
  Value_2 = sample(c("X", "Y", "Z", "W"), length(dates), replace = TRUE)
)


sidebar <- dashboardSidebar(
  sidebarMenu(
    id= "sidebarID",
    conditionalPanel(
      condition="input.sidebarID =='menu1'",
      dateRangeInput("complaints_date_range","Select Date Range",
                     start=max(df$Week),
                     end=max(df$Week),
                     min=max(df$Week),
                     max=max(df$Week),
                     format="yyyy-mm-dd"
                     )
    ),
    menuItem("Menu Item 1",tabName="menu1"),
    menuItem("Menu Item 2",tabName="menu2")
  )
)

body<- dashboardBody(
  tabItems(
    tabItem(tabName="menu1",
            tabsetPanel(
              tabPanel("Tab 1"),
              tabPanel("Tab 2")
            )),
    tabItem(tabName="menu2")
  )
)

ui<-dashboardPage(
  dashboardHeader(title="Navigation"),
  sidebar,
  body
)

server<-function(input,output,session){
  
  
  
}

shinyApp(ui,server)

我尝试了许多不同的尝试，涉及条件面板中的不同条件，但没有任何效果。

Answer 1

如果你的内部标签有一个ID

body<- dashboardBody(
  tabItems(
    tabItem(tabName="menu1",
            tabsetPanel(id="innerTab",
              tabPanel("Tab 1"),
              tabPanel("Tab 2")
            )),
    tabItem(tabName="menu2")
  )
)

然后在渲染的条件下使用它

conditionalPanel(
      condition="input.sidebarID =='menu1' & input.innerTab=='Tab 1'",
      ...
)
