问题描述

是否可以阻止shinydashboardPlus中的右侧边栏隐藏应用程序的部分正文？

常规左侧栏面板的默认行为是不隐藏应用程序主体的任何部分。例如，在下图中，单击左侧侧边栏，将绘图移到右侧(您可以看到绘图的所有部分)。

单击右侧工具栏面板时，不会发生此行为(请参见下面的屏幕截图)。

单击侧边栏，部分绘图被面板隐藏。我如何才能停止此行为并使其在单击后向左移动/重新缩放以适应身体，这样我就不会隐藏部分情节？

示例代码

library(shiny)
library(shinydashboard)
library(shinydashboardPlus)
data(iris)

header <- dashboardHeaderPlus(
  enable_rightsidebar = TRUE,
  rightSidebarIcon = "filter"
)

sidebar <- dashboardSidebar(selectInput(inputId = "slect",
                                        label = "Selection Menu", 
                                        selected = "a",
                                        choices = LETTERS[1:3])
)

body <- dashboardBody(fluidPage(plotOutput( "scatter", 
                                  height = "700px", 
                                  width = "700px")))

rightsidebar <- rightSidebar()

ui <- dashboardPagePlus(header, 
                        sidebar, 
                        body, 
                        rightsidebar)

server <- function(input, output) {
    output$scatter <- renderPlot({
    plot(iris$Petal.Length, iris$Petal.Width, pch=21)
      cats <- levels(iris$Species)
      cols <- c("red", "blue", "yellow2")
      ind <- lapply(cats, function(z) which(iris$Species == z))
      for (i in seq(cats)) {
        points(iris$Petal.Length[ind[[i]]], iris$Petal.Width[ind[[i]]], 
               pch = 19, col = cols[i])
      }
    })
}

shinyApp(ui, server)

推荐答案

第一个问题是，如果您希望调整plotOutput的大小，plotOutput不应该具有700px的固定宽度。

第二个问题是，点击右边栏不会触发shinydashboard左边栏的调整大小事件(与here相同)。我通过js：

library(shiny)
library(shinydashboard)
library(shinydashboardPlus)
data(iris)

header <- dashboardHeaderPlus(enable_rightsidebar = TRUE,
                              rightSidebarIcon = "filter")

sidebar <- dashboardSidebar(
  selectInput(
    inputId = "slect",
    label = "Selection Menu",
    selected = "a",
    choices = LETTERS[1:3]
  )
)

body <- dashboardBody(
  tags$script('
      $(".navbar-custom-menu").on("click",function(){
        $(window).trigger("resize");
      })'
  ),
  fluidPage(
    plotOutput(
      "scatter",
      height = "700px",
      width = "100%"
    )
  ))

rightsidebar <- rightSidebar()

ui <- dashboardPagePlus(header,
                        sidebar,
                        body,
                        rightsidebar)

server <- function(input, output) {
  output$scatter <- renderPlot({
    plot(iris$Petal.Length, iris$Petal.Width, pch = 21)
    cats <- levels(iris$Species)
    cols <- c("red", "blue", "yellow2")
    ind <- lapply(cats, function(z)
      which(iris$Species == z))
    for (i in seq(cats)) {
      points(iris$Petal.Length[ind[[i]]],
             iris$Petal.Width[ind[[i]]],
             pch = 19,
             col = cols[i])
    }
  })
}

shinyApp(ui, server)
