Autocomplete shows only message N results are available, use up and down arrow keys to navigate. instead show list
Just check if you are importing the correct css to correct the list rendering
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css"/> <script src="http://code.jquery.com/jquery-1.9.1.js"></script> <script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script> <link rel="stylesheet" href="/resources/demos/style.css" />And if you also want to remove the message, add the following entry after source
$("#fcb").autocomplete({ //your source info messages: { noResults: '', results: function() {} }});
Check your CSS, maybe you are hiding the menu element. Try with:
.ui-autocomplete { z-index: 10000000;}
