renderUI {shiny} | R Documentation

## UI Output

### Description

Experimental feature. Makes a reactive version of a function that generates 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 environment in which to evaluate `expr`.
`quoted` | Is `expr` a quoted expression (with `quote()`)? This is useful if you want to save an expression in a variable.
`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`).

    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)
    }
