One more example

Autocompleter for the first name input with caching, match highlighting and 5 results limit. Remote response depends on a gender:

Form markup

<label for="gender_male">Male</label>
<input type="radio" name="gender" value="male" id="gender_male" checked="checked">

<label for="gender_female">Female</label>
<input type="radio" name="gender" value="female" id="gender_female">

<label for="firstname">First Name</label>
<input type="text" name="firstname" id="firstname">

Code

$(function() {
  $('#firstname').autocompleter({
    limit: 5,
    cache: true,
    combine: function(params) {
      var gender = $('input:radio[name=gender]:checked').val();

      return {
        q: params.query,
        count: params.limit,
        gender: gender
      };
    },
    callback: function(value, index, object) {
      console.log(
        'Value ' + value + ' are selected (with index ' + index + ').'
      );
      console.log(object);
    }
  });
});

Markup

div (node) -> ul (list) -> li (item).

<div class="autocompleter" id="autocompleter-1">
	<ul class="autocompleter-list">
		<li class="autocompleter-item">First</li>
		<!-- ... -->
		<li class="autocompleter-item">Last</li>
