module.file	Name of file found within module directories that contains UI code
numbered	If TRUE, directories will be ordered by numeric prefix (e.g., 01_Index, 02_About)

...	Additional arguments to be passed to the supplied layout.fun

Value

A Shiny UI object

Examples

# app.R
# Create a UI object and render it

server <- function(input, output, session) {
  output$appUI <- renderUI({
    modularUI(
      module.dir = file.path('.', 'modules'),
      module.file = 'ui.R',
      layout.fun = navbarPage,
      title = 'My Modular App'
