I'm using pageWithSidebar with a sidebar on the left. Now I'd like to add button on the top right side of the page. How could I achieve this? http://shiny.rstudio.com/reference/shiny/latest/pageWithSidebar.html I found dashboard but the structure doesn't look the sames as regular shiny. https://rstudio.github.io/shinydashboard/structure.html
  navbarPage(
title = 'DataTable Options',
tabPanel('Display length',     DT::dataTableOutput('ex1')),
tabPanel('Length menu',        DT::dataTableOutput('ex2')),
tabPanel('No pagination',      DT::dataTableOutput('ex3')),
tabPanel('No filtering',       DT::dataTableOutput('ex4')),
tabPanel('Function callback',  DT::dataTableOutput('ex5'))
)pageWithSidebar(
 headerPanel("test"),
  sidebarPanel(
textInput("globalSearch", "Search", "")))
