updateF7Slider(
  inputId,
  min = NULL,
  max = NULL,
  value = NULL,
  scale = FALSE,
  scaleSteps = NULL,
  scaleSubSteps = NULL,
  step = NULL,
  color = NULL,
  session = shiny::getDefaultReactiveDomain()
)

Arguments

inputId	The id of the input object.
min	Slider minimum range.
max	Slider maximum range
value	Slider value or a vector containing 2 values (for a range).
scale	Slider scale.
scaleSteps	Number of scale steps.
scaleSubSteps	Number of scale sub steps (each step will be divided by this value).
