UI Output

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.

Description

Experimental feature. Makes a reactive version of a function that generates HTML using the Shiny UI library.

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) }
