Update a glassSelect widget

Update the available choices, current selection, and/or selection-marker style of an existing glassSelect() input.

Usage

updateGlassSelect(
  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 value, or NULL to keep the 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.

Value

No return value. Called for its side effect of updating the client-side widget.

Details

This function follows Shiny-style update semantics:

• choices = NULL leaves choices unchanged

• selected = NULL leaves selection unchanged

• selected = character(0) clears the selection

• check_style = NULL leaves the current style unchanged

When choices is supplied and selected is not, the browser side keeps the current selection if it is still present in the new choices.
