如何从multiInput包中更改shinyWidgets ()的字体颜色

Question

我有下面的应用程序使用shinyWidgets包

library(shinyWidgets); library("shiny")
ui <- fluidPage(
  multiInput(
    inputId = "id", label = "Fruits :",
     choices = c("Banana", "Blueberry", "Cherry",
                "Coconut", "Grapefruit", "Kiwi",
                "Lemon", "Lime", "Mango", "Orange",
                "Papaya"),
    selected = "Banana", width = "400px",
     options = list(
       enable_search = FALSE,
       non_selected_header = "Choose between:",
      selected_header = "You have selected:"
    )
   ),
   verbatimTextOutput(outputId = "res")
 )

 server <- function(input, output, session) {
   output$res <- renderPrint({
     input$id
  })
 }

shinyApp(ui = ui, server = server)

是否有可能进一步定制。特别是我想改变字体颜色为黑色的所有选择。我在下面添加了一行，但是它未能更改字体颜色。

tags$head(tags$style(HTML('#id {color:#000 !important;}'))),

任何指针都将受到高度赞赏。

使用此CSS：

css <- "#id+div div a {color: black;}"

ui <- fluidPage(
  tags$head(tags$style(css)),
  ......
