css - Shiny 应用程序中的可折叠框

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)

这个结果是

在上图中，当单击最小化按钮时，可折叠框不会折叠。

我已经在工作目录中添加了附加的 AdminLTE.css 和 shinydashboard.css 文件，但问题仍然存在。

仅在 shiny 内使用可折叠框。我们需要添加所需的 javascript。在添加 css 之后，我们添加 this文件也是如此。

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

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