R_shiny: Web Application Framework for R

Description Usage Arguments Details See Also Examples

Dynamically hide or show a tabPanel (or a navbarMenu)from an existing tabsetPanel, navlistPanel or navbarPage.

showTab(inputId, target, select = FALSE,
  session = getDefaultReactiveDomain())

hideTab(inputId, target, session = getDefaultReactiveDomain())

`inputId`	The `id` of the `tabsetPanel` (or `navlistPanel` or `navbarPage`) in which to find `target`.
`target`	The `value` of the `tabPanel` to be hidden/shown. See Details if you want to hide/show an entire `navbarMenu` instead.
`select`	Should `target` be selected upon being shown?
`session`	The shiny session within which to call this function.

For navbarPage, you can hide/show conventional tabPanels (whether at the top level or nested inside a navbarMenu), as well as an entire navbarMenu. For the latter case, target should be the menuName that you gave your navbarMenu when you first created it (by default, this is equal to the value of the title argument).
