Auto complete text field in Shiny

Question

This question is inspired by, though not the same as this. Specifically, I wish to match all "Maples" not just where "Maple" is the first word.

I am using a text field to help a user select a common tree name. There are 246 choices. So, I would like to use type ahead to help the user find a tree.

If a user types maple, the auto selection should include trees like: Maple, Sugar Maple, Norway Maple

However the code below using the shinysky package doesn't search past the first word. Is there a work around for this? Is shinysky the right approach here? Would selectizeInput() be better?

library(shinysky)
library(shiny)
library(tidyverse)

my_data <- read.csv("common_tree_names_246.csv", header = FALSE)$V1
my_list <- as.character(my_data)

ui <- shinyUI(
  fluidPage(tags$style(type="text/css",".shiny-output-error { visibility: hidden; }",".shiny-output-error:before { visibility: hidden; }"),
            tags$style(type="text/css","#search { top: 50% !important;left: 50% !important;margin-top: -100px !important;margin-left: -250px 
                       !important; color: red; font-size: 5px; font-style: italic;}"),         

            mainPanel(  
              # one way of doing it
              textInput.typeahead(id = "search",
                                  placeholder = "Tree type?",
                                  local = data.frame(name = c(my_list)),
                                  valueKey = "name",
                                  tokens = c(1:length(my_list)),
                                  template = HTML("<p class='repo-language'>{{info}}</p> <p class='repo-name'>{{name}}</p>")
                                  )
                    )
            )
)

server <- function(input, output, session) {}
shinyApp(ui = ui, server = server)

Answer 1

one way of doing this: 1-read your data in the server.r file 2-make a textinput module in server.r file

in server.r :

library(shiny)
library(shinydashboard)

function(input, output){

  my_list <- reactive({
    data <- read.csv("common_tree_names_246.csv", header = FALSE)$V1
    my_list <- as.character(data)

  })

  output$tree <- renderUI({

    selectInput(inputId = "tree", label = "Trees", choices = my_list())
  })
}

and in ui.r:

library(shiny)
library(shinydashboard)

dashboardPage(
    dashboardHeader(),
    dashboardSidebar(),
    dashboardBody(
      uiOutput("tree")
    )
)
