SelectInput under menuitem is not working - r

Question

There is a wrong display in shiny dashboard for the below code. The title "Yet to do" is getting displayed as soon as i run the app. I need that when I click on Bivariate Analysis. What is the issue here. This happened when I introduced selectinput under menu item. Earlier it was working well
library(shinydashboard)
library(shiny)
ui <- dashboardPage(
dashboardHeader(title = "Data Analysis"),
dashboardSidebar(
sidebarMenu(
menuItem("Univariate Analysis", tabName = "Univariate", icon =
icon("question"),selectInput("Factors",h5("Factors"),choices =
c("","A","B"))),
menuItem("Bivariate Analysis", tabName = "Bivariate", icon =
icon("question")))
),
dashboardBody(
tabItems(
tabItem(tabName = "Univariate",fluidRow(box(plotOutput("Plot1"),width =
1000,height = 1000),
box(plotOutput("Plot2"),width =
1000,height = 1000))),
tabItem(tabName = "Bivariate",h1("Yet to do")))
))
server <- function(input, output) {
}
shinyApp(ui, server)

It is related having selectInput() as menuItem(). I tried some options like creating menuSubItem etc. but couldn't get it to work. This is probably some bug so you may have to look around for a fix. For now, I'd suggest moving the selectInput inside dashboardBody() -
ui <- dashboardPage(
dashboardHeader(title = "Data Analysis"),
dashboardSidebar(
sidebarMenu(
menuItem("Univariate Analysis",
tabName = "Univariate", icon = icon("question")
# removing selectInput from here fixes the issue
# ,selectInput("Factors", h5("Factors"), choices = c("","A","B"))
),
# an option is to have selectInput by itself but probably not the layout you want
# selectInput("Factors", h5("Factors"), choices = c("","A","B")),
menuItem("Bivariate Analysis",
tabName = "Bivariate", icon = icon("question")
)
)
),
dashboardBody(
tabItems(
tabItem(tabName = "Univariate",
fluidRow(
# add selectInput somewhere on Univariate page
selectInput("Factors", h5("Factors"), choices = c("","A","B")),
box(plotOutput("Plot1"), width = "50%", height = "50%"),
box(plotOutput("Plot2"), width = "50%", height = "50%")
)
),
tabItem(tabName = "Bivariate",
h1("Yet to do")
)
)
)
)
server <- function(input, output) {}
shinyApp(ui, server)
