css 闪亮的selectInput/pickerInput带有长名称的输入应溢出边栏

我想用bs4Dash在侧边栏布局中构建一个闪亮的应用程序。侧边栏包含一个下拉菜单,其中的项目有很长的名称。一旦我打开下拉菜单,我希望完整的项目名称是可见的,例如,溢出 Jmeter 板的主体。默认情况下,名称在侧边栏边界处被剪切(shiny::selectizeInput),或者下拉内容与侧边栏边框右对齐,并且项目名称的开头在屏幕外靠左(shinyWidgets::pickerInput)。
这是应用程序的外观(更新日期:2022 - 12 - 16):

我试图将该解决方案应用于描述为hereflexdashboard,但无法使其工作。
谢谢你的帮忙!
下面是我的应用程序的一个可复制示例:

# app.R
library(shiny)
library(bs4Dash)
library(shinyWidgets)

vec_long_items <- sapply(1:10, function(i) {
  paste("START", paste(sample(letters, 100, replace = TRUE), collapse = ""))
})

shinyApp(
  ui = dashboardPage(
    header = bs4DashNavbar(
      title = "Long items to select", disable = TRUE, controlbarIcon = NULL
    ),
    sidebar = bs4DashSidebar(
      skin = "white",
      shinyWidgets::pickerInput(
        inputId = "in1", label = "shinyWidgets::pickerInput", choices = vec_long_items
      ),
      shiny::selectInput(
        inputId = "in2", label = "shiny::selectInput", choices = vec_long_items
      )
    ),
    body = dashboardBody(tableOutput("out_text"))
  ),
  server = function(input, output, session) {
    output$out_text <- renderTable(data.frame(items = vec_long_items))
  },
  options = list(launch.browser = FALSE)
)

试试这个css:

css <- ".main-sidebar, .main-sidebar .sidebar .os-viewport, .os-host-overflow, .os-host-overflow>.os-padding {overflow: visible !important;}"

body = dashboardBody(
      tags$head(
        tags$style(HTML(css))
      ),

以及

shinyWidgets::pickerInput(
        inputId = "in1", label = "shinyWidgets::pickerInput", choices = vec_long_items, 
        options = pickerOptions(dropdownAlignRight = TRUE)
      ),

我发现pickerInput的一个CSS属性可以改进输出。按如下所示更改正文:

# ...
body = dashboardBody(
      tags$head(
        tags$style(HTML("
        .dropdown-menu.show {
          display: contents;
        }
      "))
      ),
      tableOutput("out_text")
    )
# ...

现在有一个滚动条来查看完整的元素。不是我想要的,但已经更好了。

我仍然在寻找一个“溢出解决方案”:-)
