具有长名称的闪亮 selectInput/pickerInput 应该溢出侧边栏

Question

我想在侧边栏布局中使用 bs4Dash 构建一个闪亮的应用程序。侧边栏包含一个下拉选择菜单，其中包含长名称的项目。打开下拉菜单后，我希望完整的项目名称可见，即溢出仪表板的主体。默认情况下，名称会在侧边栏边框处剪切 (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位于屏幕左侧 (shinyWidgets::pickerInput)。< /p>

这是应用程序的外观（更新于 2022 年 12 月 16 日）：

我尝试将解决方案应用于 flexdashboard 描述的 这里， 但无法让它工作。

感谢您的帮助！

这是我的应用程序的可重现示例：

# 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)
)

Answer 1

试试这个CSS：

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

即

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

和

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