Optional Slider Input Widget

Description

Hidden input widgets are useful to have the input[[inputId]] variable on available in the server function but no corresponding visual clutter from input widgets that provide only a single choice.

Usage

optionalSliderInput(inputId, label, min, max, value, label_help = NULL, ...)

Arguments

inputId	The input slot that will be used to access the value.
label	Display label for the control, or NULL for no label.
min, max	The minimum and maximum values (inclusive) that can be selected.
value	The initial value of the slider, either a number, a date (class Date), or a date-time (class POSIXt). A length one vector will create a regular slider; a length two vector will create a double-ended range slider. Must lie between min and max.
label_help	(shiny.tag) optional object of class shiny.tag, e.g. an object returned by shiny::helpText()
...	optional arguments to sliderInput

Details

if min or max are NA then the slider widget will be hidden

Value

(shiny.tag) HTML tag with sliderInput widget.

  shinyjs::useShinyjs(),
  optionalSliderInput("s", "shown", 0, 1, 0.2),
  optionalSliderInput("h", "hidden", 0, NA, 1),
