R: UI Output

renderUI {shiny}

R Documentation

UI Output

Description

Renders reactive HTML using the Shiny UI library.

Usage

renderUI(expr, env = parent.frame(), quoted = FALSE, outputArgs = list())

Arguments

`expr`	An expression that returns a Shiny tag object, `HTML()`, or a list of such objects.
`env`	The parent environment for the reactive expression. By default, this is the calling environment, the same as when defining an ordinary non-reactive expression. If `expr` is a quosure and `quoted` is `TRUE`, then `env` is ignored.
`quoted`	If it is `TRUE`, then the `quote()`ed value of `expr` will be used when `expr` is evaluated. If `expr` is a quosure and you would like to use its expression as a value for `expr`, then you must set `quoted` to `TRUE`.
`outputArgs`	A list of arguments to be passed through to the implicit call to `uiOutput()` when `renderUI` is used in an interactive R Markdown document.

Details

The corresponding HTML output tag should be div and have the CSS class name shiny-html-output (or use uiOutput()).

Examples

## Only run examples in interactive R sessions
if (interactive()) {

ui <- fluidPage(
  uiOutput("moreControls")
)

server <- function(input, output) {
  output$moreControls <- renderUI({
    tagList(
      sliderInput("n", "N", 1, 1000, 500),
      textInput("label", "Label")
    )
  })
}
shinyApp(ui, server)
}
