I know that your problem has been solved and that you probably won't change your code ~1years later, but for others like me encountering this problem I have a simpler solution.

You have to wrap all "menuItem" in the sideBarMenu() fonction. This will solve the problem and make the items in the menu bigger.

library(shiny)
library(shinydashboard)

shinyUI(dashboardPage(skin = "black",
dashboardHeader(title = h4("Tableau de bord des élections",style =      
"color:navy"),
titleWidth = 300
),
dashboardSidebar(id="", sidebarMenu(
menuItem(h4(strong("Dashboard", align = "center")), tabName = "dashboard"),
menuItem(h4(strong("Prédiction")), tabName = "Prédiction"),
menuItem(h4(strong("Interprétation")), tabName = "Interprétation"))),

dashboardBody(
tabItems(
    tabItem(tabName = "dashboard",h2("Analyse du comportement électoral  des citoyens tunisiens", align="center",style = "color:navy") ),

    tabItem(tabName = "Prédiction", h2("Prédiction du vote",    align="center",style = "color:blue")),
    tabItem(tabName = "Interprétation", h2("Interprétation"))

    )
)))
