\usage{
insertTab(
inputId,
tab,
target,
position = c("before", "after"),
select = FALSE,
session = getDefaultReactiveDomain()
)
prependTab(
inputId,
tab,
select = FALSE,
menuName = NULL,
session = getDefaultReactiveDomain()
)
appendTab(
inputId,
tab,
select = FALSE,
menuName = NULL,
session = getDefaultReactiveDomain()
)
removeTab(inputId, target, session = getDefaultReactiveDomain())
}
\arguments{
\item{inputId}{The \code{id} of the \code{tabsetPanel} (or
\code{navlistPanel} or \code{navbarPage}) into which \code{tab} will
be inserted/removed.}
\item{tab}{The item to be added (must be created with \code{tabPanel},
or with \code{navbarMenu}).}
\item{target}{If inserting: the \code{value} of an existing
\code{tabPanel}, next to which \code{tab} will be added.
If removing: the \code{value} of the \code{tabPanel} that
you want to remove. See Details if you want to insert next to/remove
an entire \code{navbarMenu} instead.}
\item{position}{Should \code{tab} be added before or after the
\code{target} tab?}
\item{select}{Should \code{tab} be selected upon being inserted?}
\item{session}{The shiny session within which to call this function.}
\item{menuName}{This argument should only be used when you want to
prepend (or append) \code{tab} to the beginning (or end) of an
existing \code{\link[=navbarMenu]{navbarMenu()}} (which must itself be part of
an existing \code{\link[=navbarPage]{navbarPage()}}). In this case, this argument
should be the \code{menuName} that you gave your \code{navbarMenu}
when you first created it (by default, this is equal to the value
of the \code{title} argument). Note that you still need to set the
\code{inputId} argument to whatever the \code{id} of the parent
\code{navbarPage} is. If \code{menuName} is left as \code{NULL},
\code{tab} will be prepended (or appended) to whatever
\code{inputId} is.}
}
\description{
Dynamically insert or remove a \code{\link[=tabPanel]{tabPanel()}} (or a
\code{\link[=navbarMenu]{navbarMenu()}}) from an existing \code{\link[=tabsetPanel]{tabsetPanel()}},
\code{\link[=navlistPanel]{navlistPanel()}} or \code{\link[=navbarPage]{navbarPage()}}.
}
\details{
When you want to insert a new tab before or after an existing tab, you
should use \code{insertTab}. When you want to prepend a tab (i.e. add a
tab to the beginning of the \code{tabsetPanel}), use \code{prependTab}.
When you want to append a tab (i.e. add a tab to the end of the
\code{tabsetPanel}), use \code{appendTab}.
For \code{navbarPage}, you can insert/remove conventional
\code{tabPanel}s (whether at the top level or nested inside a
\code{navbarMenu}), as well as an entire \code{\link[=navbarMenu]{navbarMenu()}}.
For the latter case, \code{target} should be the \code{menuName} that
you gave your \code{navbarMenu} when you first created it (by default,
this is equal to the value of the \code{title} argument).
