Installation

Include jQuery if it's still not included. The easiest way is to use some public CDN.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

Download latest ikSelect script from here

Include ikSelect script after jQuery

<script src="ikSelect.min.js"></script>

Initialize the script somewhere. Better do it after the DOM is ready.
```
$(function () {
	$('select').ikSelect();
});
```

Add some CSS

.ik_select {
	/*
	Wraps all the plugin's HTML code.
	Probably you should not add any styles here
	*/
}
	.ik_select_link {
		/* Fake select you click on to open the dropdown */
	}
	.ik_select_link_focus {
		/* Focused state of the fake select */
	}
	.ik_select_link_disabled {
		/* Disabled state of the fake select */
	}
		.ik_select_link_text {
			/*
			Wrapper for the text inside the link.
			It's best to add some width limiting rules here like
			display:block;
			overflow:hidden;
			white-space:nowrap;
			text-overflow:ellipsis;
			*/
		}

	.ik_select_dropdown {
		/*
		Dropdown wrapper. Needed for script calculations.
		You should not add any visual styles here.
		You can shift the position of the dropdown
		by changing top and left values like
		top: -2px;
		left: -5px;
		*/
	}
		.ik_select_list {
			/*
			Wrapper for the options list.
			Now that's a good place to add visual styles.
			*/
		}
			.ik_select_optgroup {
				/* Optgroup */
			}
				.ik_select_optgroup_label {
					/* Optgroup label */
				}
				.ik_select_option {
					/* Option */
				}
					.ik_select_option_label {
						/* Option label */
					}
				.ik_select_hover {
					/* The hovered state of an option */
				}
				.ik_select_active {
					/* The active state of an option */
				}

		.ik_select_filter_wrap {
			/* Wrapper for the filter input */
		}
		.ik_select_filter {
			/* Filter input */
		}
		.ik_nothing_found {
			/* Block that's shown when there's nothing found. */
		}

Options

All the options can be set using HTML5 data- attributes or as an object passed to the plugin. For the data- attibutes use lowercased options! (data-autowidth="true", data-customclass="someclass", etc)

syntax: '&lt;div class="ik_select_link"&gt;&lt;span class="ik_select_link_text"&gt;&lt;/span&gt;&lt;/div&gt;&lt;div class="ik_select_dropdown"&gt;&lt;div class="ik_select_list"&gt;&lt;/div&gt;&lt;/div&gt;'
	/*
	Custom syntax for the fake select.
	The only condition is that "ik_select_link_text" should be inside of "ik_select_link" and
	"ik_select_list" should be inside of "ik_select_dropdown".
	*/

autoWidth: true,
	/* Set width of the select according to the longest option. */

ddFullWidth: true,
	/* Set width of the dropdown according to the longest option. */

equalWidths: true,
	/* Add dropdown's scrollbar width to the fake select's width. */

dynamicWidth: false,
	/* Adjust fake select's width according to its contents. */

extractLink: false,
	/* Tells if fake select should be moved to body when clicked along with the dropdown */

customClass: '',
	/* Add custom class to the fake select's wrapper. */

linkCustomClass: '',
	/*
	Add custom class to the fake select.
	Uses customClass with '-link' appended if only the former presents.
	*/

ddCustomClass: '',
	/*
	Add custom class to the fake select's dropdown.
	Uses customClass with '-dd' appended if only the former presents.
	*/

ddMaxHeight: 200,
	/* Maximum allowed height for dropdown. */

isDisabled: false,
	/*
	Set the initial state of the select.
	Overrides the *disabled* attribute.
	*/

filter: false,
	/* Appends filter text input. */

nothingFoundText: 'Nothing found'
	/* The text to show when filter is on and nothing is found. */

Callbacks and events

After each callback there's also an event emitted. Just replace on with ik and use lowercase. (ikshow, ikkeydown, etc)

onInit: function (inst) {}
	/* Called just after plugin is initialized. */

onShow: function (inst) {}
	/* Called just after dropdown was showed. */

onHide: function (inst) {}
	/* Called just after dropdown was hidden. */

onKeyDown: function (inst) {}
	/* Called when a key on a keyboard is pressed. */

onKeyUp: function (inst) {}
	/* Called when a key on a keyboard is released. */

onHoverMove: function (inst) {}
	/* Called when some other option is hovered. */
