In glasstabs: Animated Glass-Style Tabs and Select Inputs for 'Shiny'

Register server-side search for a glassSelect widget

Description

Use this with glassSelect(..., server = TRUE) when the choice set is large. The browser sends search queries to Shiny and the server returns a bounded list of matching choices.

Usage

glassSelectServer(
  inputId,
  choices,
  session = shiny::getDefaultReactiveDomain(),
  limit = 50L,
  ignore_case = TRUE
)

Arguments

inputId	Input id used in glassSelect().
choices	Named or unnamed character vector of choices.
session	Shiny session. Defaults to the current reactive domain.
limit	Maximum number of matching choices returned per search. Default 50.
ignore_case	Logical. Match labels and values case-insensitively. Default TRUE.

Value

An observer created by shiny::observeEvent().
