Google Script - Form - live update for a text field

问题

My client has a huge list of contacts. I created a form with a scrolling list, in order to select a contact. The issue is that the scrolling list is too long. Is there a way (and if so, how?) for my client to start typing the first letters of a contact name, so the 'field area' (or other) fills in automatically the correspondant contact name? Thank you in advance for your help. Kind regards,

You can load the select with this javascript:

function updateSelect(vA)
{
  var select = document.getElementById("sel1");//or whatever you select id is
  select.options.length = 0; 
  for(var i=0;i<vA.length;i++)
  {
    select.options[i] = new Option(vA[i],vA[i]);
  }
}

The html select element:

<select id="sel1">
      <option value="" selected></option>
   </select>

I often load selects when the page loads with something like this:

$(function(){
google.script.run
          .withSuccessHandler(updateSelect)
          .getSelectOptions();//a gs function which passes an array to updateSelect via the success handler
 });

That way I can use a spreadsheet to store the values that I want. In your case you may want to filter them alphabetically perhaps. And you might want to pass the getSelectOptioptions() function or whatever you call it a parameter to determine how to filter the list.
