jQuery Pretty Dropdowns

Pretty Dropdowns is a simple, lightweight jQuery plugin that converts <select> drop-down menus into "pretty" menus that you can style using CSS.

Features:

• Two arrow styles and sizes to choose from (or add your own style)
• Support for multiple-select lists (<select multiple>)
• Support for option groups (<optgroup>)
• Tooltips (title) carried over at both <select> and <option> levels
• Full keyboard navigation (you can even go directly to a menu item by typing its text)
• Auto-linked to <label for> (menu will get focus when you click on the label)
• Accessible (it plays nicely with screen readers)
• Sensible (when you open the menu it does its best to keep the menu items within the viewport)

Getting Started

Step 1: Link the required files

<link rel="stylesheet" href="/css/prettydropdowns.css">
<script src="//code.jquery.com/jquery-2.2.4.min.js"></script>
<script src="/js/jquery.prettydropdowns.js"></script>

You have complete control over the look and feel of the drop-down menu by modifying prettydropdowns.css. It is recommended to load the JavaScript files at the bottom just before the closing </body> tag if possible.

Step 2: Call the .prettyDropdown() function

Make sure this comes after the two required JavaScript files from Step 1 are loaded.

<script>
$(document).ready(function() {
  $('select').prettyDropdown();
});
</script>

You can also specify some options:

<script>
$(document).ready(function() {
  $('select').prettyDropdown({
    height: 30
  });
});
</script>

Options

Name	Type	Default	Description
customClass	string	arrow	The class name to customize the drop-down menu style. The default arrow class displays a chevron-type arrow icon. Two additional helper classes are built in (add either or both to arrow): triangle converts the chevron into a solid triangle; small renders the arrow icon at half size.
height	number	50	The drop-down menu height. The minimum value is 8.
hoverIntent	number	200	The wait period (in milliseconds) before collapsing the drop-down menu after you hover off of it. If you hover back onto the menu within the wait period, it will remain open. The minimum value is 0.
selectedDelimiter	string	;	The separator character to use for the list of selected values in a multi-select menu.
selectedMarker	string	✓	The icon or symbol to mark that an item is selected in a multi-select menu. HTML is accepted (e.g., <i class="fa fa-check"></i>).
afterLoad	function		Callback function to execute after the drop-down menu widget is loaded.

Methods

Name	Description
refresh()	Rebuild the drop-down menu. You should do this whenever the <select> state changes (e.g., one or more <option> gets added, removed, or disabled).

Example:

<script>
$(document).ready(function() {
  $dropdown = $('select').prettyDropdown();
});
// When <select> state changes...
$dropdown.refresh();
</script>

Keyboard Navigation

Key	Description
Tab	Put focus on the next drop-down menu. If a menu is open, it will automatically close.
Shift+Tab	Put focus on the previous drop-down menu. If a menu is open, it will automatically close.
Enter	Open the drop-down menu that is in focus. If it is already open, then select the highlighted item.
Esc	Close the drop-down menu.
Home	Jump to the first item in the drop-down menu.
End	Jump to the last item in the drop-down menu.
PgUp	Go to the previous page of items. If there is no scrollbar, then this is the same as Home.
PgDn	Go to the next page of items. If there is no scrollbar, then this is the same as End.
Up	Highlight the previous item in the drop-down menu.
Down	Highlight the next item in the drop-down menu.
A-Z 0-9 Space	If the drop-down menu is open, jump to the first item matching the key(s) pressed. Every time you press a key it will cycle through the matching items. Hint: if you type fast enough, it will try to find a match for everything you typed instead of just the first character. If the menu is closed and in focus, Space opens the menu (same as Enter).

Accessibility

The following attributes are added to improve accessibility when using alternative input methods (e.g., keyboard, screen reader):

• role="listbox" and role="option" (to tell screen readers that it's a drop-down menu widget)
• aria-activedescendant (points to the currently selected menu item)
• aria-expanded (this is true when the menu is open and false when it's closed)
• aria-label (this is equivalent to the title attribute for screen readers)
• aria-labelledby (points to the <label> element that is linked to the <select> if it exists)
• tabindex="0" (to allow the widget to get focus)

Please submit an issue if there are other ways to improve accessibility.

Known Issues

• After resizing the window, the drop-down menu near the bottom of the page sometimes doesn't open in reverse.
• The multi-select container height is larger by one pixel.
• The title value will be read twice in some screen reader clients (once for title, once for aria-label).
