Question

我正在尝试制作几个滑块，标签位于滑块左侧滑块上而不是滑块上。

我看到了这两个解决方案：

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

然而，它们似乎不适用于新的闪亮模板。标签和滑块确实变成了内联，但滑块的大小确实缩小了。

如果我手动将.irs-line width设置为特定的像素数，我会得到一个合适的大小滑块，但在不同的屏幕上或者窗口最小化时看起来很糟糕。如果我尝试制作它＆＃34; auto＆＃34;或＆＃34; 100％＆＃34;，我回到了＆＃34; dot＆＃34;而不是滑块。

可重复的例子：

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在div上配置窗口小部件。例如，使用width:10vw（vw表示屏幕宽度）和height:10vh（vh表示屏幕高度）。

我应用了此代码并修改了您的代码，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)

Shiny 1.0.5使sliderInput与标签内联
