【问题描述】：

我正在使用 shinyjs 下拉按钮在闪亮仪表板中显示单选按钮。 我需要你的帮助来解决以下问题，

为下拉菜单添加垂直滚动条。

请检查我的代码，

library(shiny)
library(shinydashboard)
library(shinyjs)

ui <- dashboardPage(skin = "black",
                    dashboardHeader(title = "test"), 
                    dashboardSidebar(),
                    dashboardBody(
                                fluidRow(
                                  column(width = 1),
                                  dropdownButton(
                                    tags$h3("List of Input"),
                                    radioButtons("attr_var","", c("1","2","3","4","5","6","7","8")),
                                    circle = TRUE, status = "danger", icon = icon("gear"), width = "100px",
                                    tooltip = tooltipOptions(title = "Click to see inputs")))))

server <- function(input, output, session)  

shinyApp(ui, server)

【参考方案1】：

这是一个相当晚的答案，但诀窍是在下拉按钮中设置 max-height 和 overflow-y 值。您的代码可能如下所示：

dropdownButton(
    circle = TRUE, status = "danger", icon = icon("gear"), width = "100px",
    tooltip = tooltipOptions(title = "Click to see inputs")))),
    div(style='max-height: 80vh; overflow-y: auto;',
    tags$h3("List of Input"),
    radioButtons("attr_var","", c("1","2","3","4","5","6","7","8"))))
