Should have way to start menuItems with subitems expanded about shinydashboard

[shrektan]

I want to add should have way to start box with box collapsed. Is this possible in the current code?

@shrektan See #33.

It looks like this might require replacing the $.AdminLTE.tree function from app.js so that the expanded treeviews don't have the active class, but something else. Also it'll require some CSS to display the treeviews without the active class.

Good news! Thanks!

It would also be useful to show and highlight the newly active menuItem or menuSubItem when using
updateTabItems

The menuItem expanded/collapsed state should also be bookmarkable.

@wch I guess this means that we should also allow bookmarking of the expanded/collapsed state of the whole sidebar, right? (this may affect #186)

Note for future stumblers on this issue:

Once #199 is merged, the way to start with a "childfull" menuItem() expanded will to use the startExpanded argument. For example, in the app below, the last menuItem ("Charts") starts expanded and it's first child ("Sub-item 1") starts selected:

shinyApp(
  ui = dashboardPage(
    dashboardHeader(),
    dashboardSidebar(
      sidebarMenu(
        # Setting id makes input$tabs give the tabName of currently-selected tab
        id = "tabs",
        menuItem("Dashboard", tabName = "dashboard", icon = icon("dashboard")),
        menuItem("Widgets", icon = icon("th"), tabName = "widgets", badgeLabel = "new"),
        menuItem("Charts", icon = icon("bar-chart-o"), startExpanded = TRUE,
          menuSubItem("Sub-item 1", tabName = "subitem1", selected = TRUE),
          menuSubItem("Sub-item 2", tabName = "subitem2")
        )
      )
    ),
    dashboardBody(),
    title = "Dashboard example"
  ),
  server = function(input, output) { }
)
