i have used select2input shinysky selecting mulitiple varialbes have added submit button selected values together.

#ui.r select2input("txt","this multiple select2input",choices=c("a","b","c"),selected=c("")),  actionbutton("go","submit")

i want bind selected option lets user selected , c new variable is

#server.r input$go #if pressed submit button var<-cbind("a","c") output$text<-rendertext({ print ("var")})

but not working

look shinysky package , textinput.typeahead. can further customize style of textinput yourself. edit: added example select2input shinysky package reference 

rm(list = ls())  library(shinysky) library(shiny)  my_autocomplete_list <- c("john doe","ash","ajay sharma","ken chong","will smith","neo")  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: blue;font-size: 20px;font-style: italic;}"),                       mainpanel(                 # 1 way of doing               textinput.typeahead(id="search",                                   placeholder="type name please",                                   local=data.frame(name=c(my_autocomplete_list)),                                   valuekey = "name",                                   tokens=c(1:length(my_autocomplete_list)),                                   template = html("<p class='repo-language'>{{info}}</p> <p class='repo-name'>{{name}}</p>")               ),               br(),br(),               # using select2input               select2input("select2input1","",choices=c(my_autocomplete_list),type = c("input", "select"))               )   ) )  server <- function(input, output, session) {} shinyapp(ui = ui, server = server)

edit 2 per request. please wrap objects in reactive expressions did e.g. var <- reactive({...}) can re-use later

rm(list = ls())  library(shinysky) library(shiny)  my_autocomplete_list <- c("john doe","ash","ajay sharma","ken chong","will smith","neo")  ui <- shinyui(   fluidpage(sidebarpanel(select2input("txt","",choices=c("a","b","c"),selected=c("")), br(),actionbutton("go","submit"), width =2),             mainpanel(textoutput('text'))   ) )  server <- function(input, output, session) {    var <- reactive({     if(input$go==0){return()}     isolate({       input$go       cbind("a","c")     })   })     output$text <- rendertext({var()}) } shinyapp(ui = ui, server = server)
