Shinydashboard package not working properly

[stevietako]

Keep getting the following warning message after deploying my app:

It seems like the shinydashboard package is failing for unknown reasons. With this error, all the menuItems are listed horizontally across the entire page. Please help!

library(shinydashboard)
library(leaflet.extras2)
library(shiny)

ui <- dashboardPage(
  dashboardHeader(title = "Dynamic sidebar"),
  dashboardSidebar(
    sidebarMenuOutput("menu")
  ),
  dashboardBody()
)

server <- function(input, output) {
  output$menu <- renderMenu({
    sidebarMenu(
      menuItem("Menu item", icon = icon("calendar"))
    )
  })
}
shinyApp(ui, server)

I was not able to reproduce your error. Could you do packageVersion('shinyDashboard')?

[stevietako]

it is 0.7.2

The app seems to run properly locally, but all my menuItems() are all messed up after deployment.

Just found out the leaflet.extras2 package is what causing the problem. Both shinydashboard and leaflet.extras2 has a function called menuItem().

Adding shinydashboard::menuItem() solved the problem
