Compound input that combines and extends shiny inputs

Description

Compound input that combines and extends shiny inputs

Usage

compoundInput2(
  inputId,
  label = "Group",
  components = shiny::tagList(),
  initial_ncomp = 1,
  min_ncomp = 0,
  max_ncomp = 10,
  value = NULL,
  label_color = NA,
  max_height = NULL,
  ...
)

Arguments

inputId	character, shiny input ID
label	character, will show on each groups
components	'HTML' tags that defines and combines HTML components within groups
initial_ncomp	numeric initial number of groups to show, non-negative
min_ncomp	minimum number of groups, default is 0, non-negative
max_ncomp	maximum number of groups, default is 10, greater or equal than min_ncomp
value	list of lists, initial values of each inputs, see examples.
label_color	integer or characters, length of 1 or max_ncomp, assigning colors to each group labels; default is NA, and try to get color from foreground par("fg")
max_height	maximum height of the widget
...	will be ignored
