我想在側邊欄佈局中使用 bs4Dash 建立一個閃亮的應用程式。側邊欄包含一個下拉選擇選單,其中包含長名稱的項目。打開下拉式選單後,我希望完整的項目名稱可見,即溢出儀表板的主體。預設情況下,名稱會在側邊欄邊框處剪切(shiny::selectizeInput),或者下拉內容與側邊欄邊框右對齊,並且項目名稱的開頭位於螢幕左側(shinyWidgets::pickerInput)。 < /p>

這是應用程式的外觀(更新於 2022 年 12 月 16 日):

我嘗試將解決方案應用於 flexdashboard 描述的 這裡, 但無法讓它工作。

感謝您的幫忙!

這是我的應用程式的可重現範例:

# 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)
)

試試這個CSS:

css .os-padding {overflow: visible !important;}"

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

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