Description Usage Arguments Details See Also

A dashboardSidebar can contain a sidebarMenu. A sidebarMenu contains menuItems, and they can in turn contain menuSubItems.

sidebarMenu(..., id = NULL, .list = NULL)

menuItem(text, ..., icon = NULL, badgeLabel = NULL, badgeColor = "green",
  tabName = NULL, href = NULL, newtab = TRUE, selected = NULL,
  expandedName = as.character(gsub("[[:space:]]", "", text)),
  startExpanded = FALSE)

menuSubItem(text, tabName = NULL, href = NULL, newtab = TRUE,
  icon = shiny::icon("angle-double-right"), selected = NULL)

`...`	For menu items, this may consist of `menuSubItem`s.
`id`	For `sidebarMenu`, if `id` is present, this id will be used for a Shiny input value, and it will report which tab is selected. For example, if `id="tabs"`, then `input$tabs` will be the `tabName` of the currently-selected tab. If you want to be able to bookmark and restore the selected tab, an `id` is required.
`.list`	An optional list containing items to put in the menu Same as the `...` arguments, but in list format. This can be useful when working with programmatically generated items.
`text`	Text to show for the menu item.
`icon`	An icon tag, created by `icon`. If `NULL`, don't display an icon.
`badgeLabel`	A label for an optional badge. Usually a number or a short word like "new".
`badgeColor`	A color for the badge. Valid colors are listed in validColors.
`tabName`	The name of a tab that this menu item will activate. Not compatible with `href`.
`href`	An link address. Not compatible with `tabName`.
`newtab`	If `href` is supplied, should the link open in a new browser tab?
`selected`	If `TRUE`, this `menuItem` or `menuSubItem` will start selected. If no item have `selected=TRUE`, then the first `menuItem` will start selected.
`expandedName`	A unique name given to each `menuItem` that serves to indicate which one (if any) is currently expanded. (This is only applicable to `menuItem`s that have children and it is mostly only useful for bookmarking state.)
`startExpanded`	Should this `menuItem` be expanded on app startup? (This is only applicable to `menuItem`s that have children, and only one of these can be expanded at any given time).

Menu items (and similarly, sub-items) should have a value for either href or tabName; otherwise the item would do nothing. If it has a value for href, then the item will simply be a link to that value.

If a menuItem has a non-NULL tabName, then the menuItem will behave like a tab – in other words, clicking on the menuItem will bring a corresponding tabItem to the front, similar to a tabPanel. One important difference between a menuItem and a tabPanel is that, for a menuItem, you must also supply a corresponding tabItem with the same value for tabName, whereas for a tabPanel, no tabName is needed. (This is because the structure of a tabPanel is such that the tab name can be automatically generated.) Sub-items are also able to activate tabItems.
