我想放一个 selectInput 还有 actionButton 并排在我的 shinydashboard::box .按钮应“相对靠近”屏幕 选择输入 无关的 盒子的宽度。

到目前为止我都试过了

到目前为止我试过了 column , splitLayout 或者通过 display: inline-block ,但我对以下两种解决方案都不满意:

柱 :根据盒子的宽度,盒子之间的间隙 选择输入 和 动作按钮 太大了(我可以通过扩展 选择输入 宽度为100%,但宽度太大)
splitDesign :目前为止最好的选择,但是 cellWidths 基于box的需求调整 width 而且只适用于100% 选择输入 宽度对于大盒子来说,第二次分割的宽度似乎太大了
inline-block CSS

library(shiny)
library(purrr)
library(shinydashboard)

widths <- c(1, 2,3, 4, 6, 12)

makeBoxes <- function(width, method = c("split", "col", "css")) {
   method <- match.arg(method)
   split <- function(width, count) {
      splitLayout(selectInput(paste("sel", width, count, sep = "_"), NULL, LETTERS,
                              width = "100%"),
                  actionButton(paste("ab", width, count, sep = "_"), icon("trash")),
                  cellWidths = c("87.5%", "12.5%"),
                  cellArgs = list(style = "vertical-align: top"))
   }
   col <- function(width, count) {
      fluidRow(column(width = 11,
                      selectInput(paste("sel", width, count, sep = "_"), NULL, LETTERS,
                                  width = "100%")),
               column(width = 1,
                      actionButton(paste("ab", width, count, sep = "_"), icon("trash"))))
   }

   css <- function(width, count) {
      fluidRow(div(selectInput(paste("sel", width, count, sep = "_"), NULL, LETTERS),
                   style = "display: inline-block; vertical-align: top"),
               actionButton(paste("ab", width, count, sep = "_"), icon("trash")))
   }

   map(seq(1, 12 / width, 1), function(count)
      box(solidHeader = TRUE, title = "Box", status = "info", width = width,
          footer = wrap(method, width, count)))
}

server <- function(input, output) {
}

ui1 <- dashboardPage(dashboardHeader(), dashboardSidebar(),

我希望这会有用。我把宽度=11改为12,这对我来说很好。

这就是你想要的吗?

library(shiny)
library(purrr)
library(shinydashboard)

widths <- c(1, 2,3, 4, 6, 12)

makeBoxes <- function(width, method = c("split", "col", "css")) {
method <- match.arg(method)
split <- function(width, count) {
  splitLayout(selectInput(paste("sel", width, count, sep = "_"), NULL, LETTERS,
                          width = "100%"),
              actionButton(paste("ab", width, count, sep = "_"), icon("trash")),
              cellWidths = c("87.5%", "12.5%"),
              cellArgs = list(style = "vertical-align: top"))
}
col <- function(width, count) {
  fluidRow(column(width = 12,  # width = 11 -> 12
                  selectInput(paste("sel", width, count, sep = "_"), NULL, LETTERS,
                              width = "100%")),
           column(width = 1,
                  actionButton(paste("ab", width, count, sep = "_"), icon("trash"))))
}

 css <- function(width, count) {
  fluidRow(div(selectInput(paste("sel", width, count, sep = "_"), NULL, LETTERS),
               style = "display: inline-block; vertical-align: top"),
           actionButton(paste("ab", width, count, sep = "_"), icon("trash")))
}

 wrap <- function(method, ...)
  switch(method, split = split(...), col = col(...), css = css(...))

map(seq(1, 12 / width, 1), function(count)
  box(solidHeader = TRUE, title = "Box", status = "info", width = width,
      footer = wrap(method, width, count)))
}

server <- function(input, output) {
}

ui2 <- dashboardPage(dashboardHeader(), dashboardSidebar(),
                 dashboardBody(map(widths, ~ fluidRow(makeBoxes(.x, "col")))))

shinyApp(ui2, server)
