Shiny 1.0.5 使滑块输入与标签内联

Question

我正在尝试制作几个滑块，其中标签位于滑块的左侧而不是顶部。

我看到了这两个解决方案：

https://github.com/rstudio/shiny/issues/1737

selectInput 旁边的标签闪亮

但是，它们似乎不适用于新的闪亮模板。标签和滑块确实成为内联的，但滑块的尺寸确实缩小了。

如果我手动将 .irs-line 宽度设置为特定数量的像素，我会得到一个合适大小的滑块，但它在不同的屏幕上或窗口被最小化时看起来很糟糕。如果我尝试将其设为“自动”或“100%”，我将回到“点”而不是滑块。

可重现的例子：

library(shiny)

ui <- fluidPage(
  sidebarPanel(
    width = 4,
    div(HTML("<b>Bla bla bla bla bla</b>")),
    br(),
    tags$head(
      tags$style(type="text/css", 
                 "label.control-label, .selectize-control.single { 
                 display: table-cell; 
                 text-align: center; 
                 vertical-align: middle; 
                 } 
                 label.control-label {
                 padding-right: 10px;
                 }
                 .form-group { 
                 display: table-row;
                 }
                 .selectize-control.single div.item {
                 padding-right: 15px;
                 }
                 .irs-line{
                 width: 100%;
                 }")
    ),
    sliderInput("lbl1", "label 1", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl2", "label 2", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl3", "label 3", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl4", "long label number 4", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl5", "label 5", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl6", "label 6", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl7", "label 7", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl8", "label 8", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl9", "label 9", min = 0, max = 10, value = 0, step = 1)
  )
)
)

server <- function(input, output) {

}

shinyApp(ui = ui, server = server)

我不是专家，但我会分享我所知道的：

您始终可以使用相对大小来配置 div 上的小部件。使用例如width:10vw（vw 指您的屏幕宽度）和height:10vh（vh 指您的屏幕高度）。

我应用了这个并修改了你的代码，似乎对我有用。

library(shiny)

ui <- fluidPage(
  sidebarPanel(
    div(style="width:10vw;",

    width = 4,
    div(HTML("<b>Bla bla bla bla bla</b>")),
    br(),
    tags$head(
      tags$style(type="text/css", 
                 "label.control-label, .selectize-control.single { 

                 text-align: center; 
                 vertical-align: middle; 
                 } 
                 label.control-label {
                 padding-right: 20vw;
                 }
                 .form-group { 
                 display: table-row;
                 }
                 .selectize-control.single div.item {
                 padding-right: 20vw;
                 }
")
    ),
    sliderInput("lbl1", "label 1", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl2", "label 2", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl3", "label 3", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl4", "long label number 4", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl5", "label 5", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl6", "label 6", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl7", "label 7", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl8", "label 8", min = 0, max = 10, value = 0, step = 1),
    sliderInput("lbl9", "label 9", min = 0, max = 10, value = 0, step = 1)
      )
    ))
  )

server <- function(input, output) {

}

shinyApp(ui = ui, server = server)
