This is the server-side function for creating a dynamic dropdown menu.
renderDropdownMenu(expr, env = parent.frame(), quoted = FALSE)
An expression that returns a Shiny tag object, HTML()
,
or a list of such objects.
The parent environment for the reactive expression. By default,
this is the calling environment, the same as when defining an ordinary
non-reactive expression. If expr
is a quosure and quoted
is TRUE
,
then env
is ignored.
If it is TRUE
, then the quote()
ed value of expr
will be used when expr
is evaluated. If expr
is a quosure and you
would like to use its expression as a value for expr
, then you must set
quoted
to TRUE
.
