着色checkboxGroupInput选择 [英] Coloring the checkboxGroupInput choices

问题描述

在我的Shiny UI中，

In my Shiny UI I have

ui <- checkboxGroupInput("my_cbgi", "Choose Something", c("A", "B", "C", "D"))

我想因此，选项（文本）A和B被涂成红色，而C和D没有被涂成红色。我尝试了HTML，但随后在UI中出现了 attribs和 children之类的奇怪框。

And I would like it so that the choices (the text) A and B are colored red, but C and D are not. I tried HTML but then in the UI weird boxes like "attribs" and "children" showed up.

预先感谢

推荐答案

由于 shiny_1.0.1 ， checkboxGroupInput 具有 choiceNames 和 choiceValues 参数用于传递任意UI以显示给用户，请查看以下示例：

Since shiny_1.0.1, checkboxGroupInput have a choiceNames and choiceValues arguments for passing arbitrary UI to display to the user, check this example :

library("shiny")

ui <- fluidPage(
  checkboxGroupInput(
    inputId = "my_cbgi",
    label = "Choose Something", 
    choiceNames = list(
      tags$span("A", style = "color: red;"),
      tags$span("B", style = "color: red;"), 
      tags$span("C", style = "color: blue;"), 
      tags$span("D", style = "font-weight: bold;")
    ),
    choiceValues = c("A", "B", "C", "D")
  )
)

server <- function(input, output) {

}

shinyApp(ui = ui, server = server)
