增加来自 ShinyBS 的 popify 弹出窗口的宽度

Question

我已经使用Shiny 包中的popify函数创建了一个弹出窗口shinyBS。我想在我的过滤器底部弹出一个与我的过滤器本身一样宽的弹出窗口。我在文档中找不到关于此的任何内容。

截屏：

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))

    }
)

你可以尝试添加一些 CSS 来做到这一点。

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，你可以添加options=list(container="body")在你popify做body的支架，其允许弹出窗口是一样大的页面。
