title: Access R Shiny selectizeInput Labels
body: <p>How can I access the Label of the selected item of a selectizeInput control in shiny from R?</p>
  
  <p>In the below example, if the user clicks on DM Ask, I would like to retrieve the value DM Ask, not DM_ask</p>
  
  <pre><code>output$group_quote_type_holder &lt;- renderUI({
  quote_type_names &lt;- c("Bid Price", "Ask Price", "DM Bid","DM Ask")
  quote_type_sql &lt;- c("price_bid","price_ask","DM_bid","DM_ask")
  names(quote_type_sql) &lt;- quote_type_names
  quote_type_named_list &lt;- quote_type_sql
  selectizeInput("group_quote_type",
               label = "Select a type:",
               choices = quote_type_named_list,
               selected = "DM_ask")
  })# end renderUI
  </code></pre>
