Update a glassMultiSelect widget — updateGlassMultiSelect • glasstabs

Update the available choices and/or current selection of an existing glassMultiSelect() input.

Usage

updateGlassMultiSelect(
  session,
  inputId,
  choices = NULL,
  selected = NULL,
  check_style = NULL
)

Arguments

session: Shiny session.
inputId: Input id of the widget.
choices: New choices, or NULL to keep current choices.
selected: New selected values, or NULL to keep current selection. Use character(0) to clear.
check_style: Optional new style string. One of "checkbox", "check-only", or "filled". Defaults to NULL, which keeps the current style unchanged.

Details

This function now follows Shiny-style update semantics more closely:

choices = NULL leaves choices unchanged
selected = NULL leaves selection unchanged
selected = character(0) clears the selection

When choices is supplied and selected is not, the browser side keeps the intersection of the current selection and the new set of choices.
