Hi mates,

I was looking for autocomplete dependent select/combobox whereby you select from buildingID dropdown and floor dropdown is automatically populated based on your selection from buildingID.

This script bellows seems to be exactly what I am looking for.

I got it from this fiddle link below:

http://jsfiddle.net/andrewwhitaker/hAM9H/

The only issue that I am having now is the black box with white down arrow.

If you mouse over it, it says, Show All Items


I can't get it to show up on the script below.

What am I missing?

  <style type='text/css'>
        .ui-button { margin-left: -1px; }
     .ui-button-icon-only .ui-button-text { padding: 0.35em; }
     .ui-autocomplete-input { margin: 0; padding: 0.48em 0 0.47em 0.45em; }
  </style>



<script type='text/javascript'>//<![CDATA[
$(window).load(function(){
    (function( $ ) {
         $.widget( "ui.combobox", {
             _create: function() {
                 var self = this,
                     select = this.element.hide(),
                     selected = select.children( ":selected" ),
                     value = selected.val() ? selected.text() : "";
                 var input = this.input = $( "<input>" )
                     .insertAfter( select )
                     .val( value )
                     .autocomplete({

Can't tell from the posted code. You have the necessary line 79: .attr( "title", "Show All Items" )

Your view source on the rendered page should show the following for the black button. Check it.

<button type="button" tabindex="-1" title="Show All Items" class="ui-button ui-widget ui-state-default ui-button-icon-only ui-corner-right ui-button-icon" role="button" aria-disabled="false">
...
</button>

EDIT: Actually, it doesn't show in view source. You need to look at it in Firebug or something similar to see the DOM elements.

I got it working now.

I needed to get 3 of the newest libraries to make this work.

<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js"></script>
<link rel="stylesheet" type="text/css" href="http://ajax.microsoft.com/ajax/jquery.ui/1.8.7/themes/black-tie/jquery-ui.css" />
