Shiny App中的可折叠盒子

Question

library(shiny)

# Define UI for application that draws a histogram
ui <- fluidPage(

  includeCSS(path = "AdminLTE.css"), #added 
  includeCSS(path = "shinydashboard.css"), #added

   # Application title
   titlePanel("Old Faithful Geyser Data"),

   # Sidebar with a slider input for number of bins 
   sidebarLayout(
      sidebarPanel(
         sliderInput("bins",
                     "Number of bins:",
                     min = 1,
                     max = 50,
                     value = 30)
      ),

      # Show a plot of the generated distribution
      mainPanel(
         box(plotOutput("distPlot"), solidHeader = T, collapsible = T, title = "collapsible box not collapsing", status = "primary")
      )
   )
)

# Define server logic required to draw a histogram
server <- function(input, output) {

   output$distPlot <- renderPlot({
      # generate bins based on input$bins from ui.R
      x    <- faithful[, 2] 
      bins <- seq(min(x), max(x), length.out = input$bins + 1)

      # draw the histogram with the specified number of bins
      hist(x, breaks = bins, col = 'darkgray', border = 'white')
   })
}

# Run the application 
shinyApp(ui = ui, server = server)

结果是

在上图中,单击mininize按钮时,可碰撞框不会折叠.

我在工作目录中添加了addtional AdminLTE.css和shinydashboard.css文件,但问题仍然存在.

Answer 1

只在闪亮的地方使用可折叠的盒子。我们需要添加所需的javascript。在添加 css 之后，我们也添加了这个文件。

  includeCSS(path = "AdminLTE.css"), #added 
  includeCSS(path = "shinydashboard.css"), #added

  #add this file and collapsible nature should work.
  includeScript(path = "app.js"), # 

Answer 2

如果您没有使用限制shinydashboard，只需创建一个没有标题和侧边栏的仪表板页面即可。它将启用 的所有功能shinydashboard，并且看起来像一个基本的闪亮应用程序。在下面的代码中，当您单击最小化/最大化按钮时，框会折叠/取消折叠。

library(shiny)
library(shinydashboard)

ui <- dashboardPage(
  dashboardHeader(disable = TRUE),
  dashboardSidebar(disable = TRUE),
  dashboardBody(
  # Application title
  titlePanel("Old Faithful Geyser Data"),
    # Sidebar with a slider input for number of bins 
    sidebarLayout(
      sidebarPanel(
         sliderInput("bins", "Number of bins:", min = 1, max = 50, value = 30)
      ),
      # Show a plot of the generated distribution
      mainPanel(
         box(plotOutput("distPlot"), solidHeader = T, collapsible = T, 
             title = "collapsible box not collapsing", status = "primary")
      )
    ) 
  )
)
# Define server logic required to draw a histogram
server <- function(input, output) {
   output$distPlot <- renderPlot({
      # generate bins based on input$bins from ui.R
      x    <- faithful[, 2] 
      bins <- seq(min(x), max(x), length.out = input$bins + 1)
      # draw the histogram with the specified number of bins
      hist(x, breaks = bins, col = 'darkgray', border = 'white')
   })
}

# Run the application 
shinyApp(ui = ui, server = server)
