闪亮的自定义selectInput/selectizeInput [英] Shiny customize selectInput/selectizeInput

问题描述

我希望将Shiny select输入到:

I want my Shiny select input to:

1. 没有标签
2. 具有自定义的背景色:#2f2d57
3. 具有占位符
4. 使用户能够输入并选择

但是，我无法使该应用程序同时遵守上述4条规则.我的代码如下:

However, I can't make the app follow the above 4 rules together. My codes are below:

数据:

table <- data.frame(col1 = c(3, 4, 8, 5, 2, 6, 7))

尝试1

问题:用户无法键入内容并从selectInput中选择

Problem: Users are unable to type-in and select from the selectInput

ui <- fluidPage(
  uiOutput("container")
)
server <- function(input, output) {

  output$container <- renderUI({
    fluidRow(
      tags$style("#three_code_zip_selector {color: #ffffff; background-color: #2f2d57;}"),
      selectInput('three_code_zip_selector', NULL, choices = c("Please Select Desired Number" = "", table$col1), selectize = F)
    )
  })
}

shinyApp(ui = ui, server = server)

尝试2

问题:通过删除 selectize = F ，用户可以键入内容进行选择，但背景颜色不会更改.

Problem: By deleting selectize = F, users can type-in to select, but the background colour is not changed.

ui <- fluidPage(
  uiOutput("container")
)
server <- function(input, output) {

  output$container <- renderUI({
    fluidRow(
      tags$style("#three_code_zip_selector {color: #ffffff; background-color: #2f2d57;}"),
      selectInput('three_code_zip_selector', NULL, choices = c("Please Select Desired Number" = "", table$col1))
    )
  })
}

shinyApp(ui = ui, server = server)

我也在尝试 selectizeInput ，但似乎仍然存在与上述相同的问题.

I was also trying selectizeInput, but seems like it still has the same problem as above.

尝试3

问题:用户可以键入，但是背景颜色没有更改，并且selectizeInput顶部有一个我不想要的标签.

Problem: Users can to type in, but the background colour is not changed, and there's a label at the top of selectizeInput which I don't want.

ui <- fluidPage(
  uiOutput("container")
)
server <- function(input, output) {

  output$container <- renderUI({
    fluidRow(
      tags$style(".selectize-dropdown-content .active {background: #2f2d57; !important;color: #ffffff; !important;}"),
  selectizeInput('three_code_zip_selector', "s", choices = c("Please Select Desired Number" = "", table$col1))
    )
  })
}

shinyApp(ui = ui, server = server)

有人对我如何满足所有这四个规则有想法吗?预先感谢！

Does anyone have ideas on how could I be able to satisfy all the 4 rules? Thanks in advance!

推荐答案

这是一个纯粹的闪亮解决方案:

Here is a pure shiny solution:

library(shiny)

table <- data.frame(col1 = c(3, 4, 8, 5, 2, 6, 7))

ui <- fluidPage(
  tags$head(tags$style(HTML('
                            #three_code_zip_selector+ div>.selectize-dropdown{background: #2f2d57; color: #ffffff;}
                            #three_code_zip_selector+ div>.selectize-input{background: #2f2d57; color: #ffffff;}
                            '))),
  selectizeInput(inputId = 'three_code_zip_selector', label = NULL, choices = table$col1, selected = NULL, multiple = TRUE, options = list('plugins' = list('remove_button'), placeholder = "Please Select Desired Number", 'create' = TRUE, 'persist' = TRUE)))


server <- function(input, output, session){}
shinyApp(ui = ui, server = server)
