从shinyBS增加popify弹出窗口的宽度

Question

我已经使用Shiny中popify包中的shinyBS函数创建了一个弹出窗口。我希望在我的过滤器底部有一个弹出窗口，它与我的过滤器本身一样宽。我在文档中找不到任何关于此的内容。

屏幕截图：

示例代码：

library(shiny)
library(shinyBS)

shinyApp(
  ui =
    fluidPage(
      sidebarLayout(
        sidebarPanel(
          tags$span(
            popify(
          sliderInput("bins",
                      "Number of bins:",
                      min = 1,
                      max = 50,
                      value = 30),
          'a very long popup',"1. I want everything behind 1 on one line and everything that starts after<br> 2. I want to see on the second line without wrapping it to the 3rd line.")),
          actionButton("tabBut", "View Table")
        ),

        mainPanel(
          plotOutput("distPlot"),
          bsModal("modalExample", "Data Table", "tabBut", size = "large",
                  dataTableOutput("distTable"))
        )
      )
    ),
  server =
    function(input, output, session) {

      output$distPlot <- renderPlot({

        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')

      })

      output$distTable <- renderDataTable({

        x    <- faithful[, 2]
        bins <- seq(min(x), max(x), length.out = input$bins + 1)

        # draw the histogram with the specified number of bins
        tab <- hist(x, breaks = bins, plot = FALSE)
        tab$breaks <- sapply(seq(length(tab$breaks) - 1), function(i) {
          paste0(signif(tab$breaks[i], 3), "-", signif(tab$breaks[i+1], 3))
        })
        tab <- as.data.frame(do.call(cbind, tab))
        colnames(tab) <- c("Bins", "Counts", "Density")
        return(tab[, 1:3])

      }, options = list(pageLength=10))

    }
)

您可以尝试添加一些CSS来执行此操作。

在侧边栏面板中，您可以添加：

tags$style(".popover{
            max-width: 100%;
          }")

如果这还不够大，您可以在options=list(container="body")中添加popify以使body成为允许弹出窗口与页面一样大的持有者。
