dragulaInput: Drag And Drop Input Widget

Description

Drag And Drop Input Widget

Usage

dragulaInput(inputId, sourceLabel, targetsLabels, targetsIds = NULL,
  choices = NULL, choiceNames = NULL, choiceValues = NULL,
  status = "primary", replace = FALSE, badge = TRUE, width = NULL,
  height = "200px")

Arguments

inputId

The input slot that will be used to access the value.

sourceLabel

Label display in the source box

targetsLabels

Labels for each target element.

targetsIds

Ids for retrieving values server-side, if NULL, the default, targetsLabels are used after removing all not-alphanumeric characters.

choices

List of values to select from (if elements of the list are named then that name rather than the value is displayed to the user). If this argument is provided, then choiceNames and choiceValues must not be provided, and vice-versa. The values should be strings; other types (such as logicals and numbers) will be coerced to strings.

choiceNames, choiceValues

List of names and values, respectively, that are displayed to the user in the app and correspond to the each choice (for this reason, choiceNames and choiceValues must have the same length). If either of these arguments is provided, then the other must be provided and choices must not be provided. The advantage of using both of these over a named list for choices is that choiceNames allows any type of UI object to be passed through (tag objects, icons, HTML code, ...), instead of just simple text.

status

If choices are displayed into a Bootstrap label, you can use Bootstrap status to color them, or NULL.

replace

When a choice is draged in a target container already containing a choice, does the later be replaced by the new one ?#'

badge

Displays choices inside a Bootstrap badge. Use FALSE if you want to pass custom appearance with choiceNames.

width

Width of the input.

height

Height of each boxes, the total input height is this parameter X 2.

Value

a UI definition
