insertUI(selector, where = c("beforeBegin", "afterBegin", "beforeEnd",
  "afterEnd"), ui, multiple = FALSE, immediate = FALSE,
  session = getDefaultReactiveDomain())
}
\arguments{
\item{selector}{A string that is accepted by jQuery's selector (i.e. the
string \code{s} to be placed in a \code{$(s)} jQuery call). This selector
will determine the element(s) relative to which you want to insert your
UI object.}

\item{where}{Where your UI object should go relative to the selector:
\describe{
  \item{\code{beforeBegin}}{Before the selector element itself}
  \item{\code{afterBegin}}{Just inside the selector element, before its
  first child}
  \item{\code{beforeEnd}}{Just inside the selector element, after its
  last child (default)}
  \item{\code{afterEnd}}{After the selector element itself}
}

\href{https://developer.mozilla.org/en-US/docs/Web/API/Element/insertAdjacentHTML}{here}.}

\item{ui}{The UI object you want to insert. This can be anything that
you usually put inside your apps's \code{ui} function. If you're inserting
multiple elements in one call, make sure to wrap them in either a
\code{tagList()} or a \code{tags$div()} (the latter option has the
advantage that you can give it an \code{id} to make it easier to
reference or remove it later on). If you want to insert raw html, use
\code{ui = HTML()}.}

\item{multiple}{In case your selector matches more than one element,
\code{multiple} determines whether Shiny should insert the UI object
relative to all matched elements or just relative to the first
matched element (default).}

\item{immediate}{Whether the UI object should be immediately inserted into
the app when you call \code{insertUI}, or whether Shiny should wait until
all outputs have been updated and all observers have been run (default).}

\item{session}{The shiny session within which to call \code{insertUI}.}

\description{
Insert a UI object into the app.
}
\details{
This function allows you to dynamically add an arbitrarily large UI
object into your app, whenever you want, as many times as you want.
Unlike \code{\link{renderUI}}, the UI generated with \code{insertUI}
is not updatable as a whole: once it's created, it stays there. Each
new call to \code{insertUI} creates more UI objects, in addition to
the ones already there (all independent from one another). To
update a part of the UI (ex: an input object), you must use the
appropriate \code{render} function or a customized \code{reactive}
function. To remove any part of your UI, use \code{\link{removeUI}}.

## Only run this example in interactive R sessions
if (interactive()) {
# Define UI
ui <- fluidPage(
  actionButton("add", "Add UI")
)

# Server logic
server <- function(input, output, session) {
  observeEvent(input$add, {
    insertUI(
      selector = "#add",
      where = "afterEnd",
      ui = textInput(paste0("txt", input$add),
                     "Insert some text")
    )
  })
}

# Complete app with UI and server components
shinyApp(ui, server)
}
