Selectonic

jQuery (Zepto) based plugin for making any list of items selectable by mouse and keyboard. It could be usefull in webapp where are different widgets like menus, dropdowns with keyboard input, lists with multiple selection and so on. It maybe too bold for just a simple menu in one place.

Features:

Single or multiple selection (uses CSS-classes);
Keyboard input like in classic filemanagers;
Possibility to set handle – elements for selecting items;
Auto-scrolling list's element and window;
And other configurable stuff.

See examples on demo page.

Getting started

Download the production version (minified) or the development version.

…or you could install it by Bower:

bower install selectonic

Use it like any jQuery (Zepto) plugin:

$(".itemsList").selectonic({
	multi: true,
    mouseMode: "standard",
    keyboard: true,
    select: function(event, ui) {
        // do something cool, for expample enable actions buttons
    },
    unselectAll: function(event, ui) {
        // …and disable actions buttons
    }
});

Do not forget some css-styling:

.j-selected {
	color: #FFFFFF;
	background-color: #2979d1;
}

Default options object accessible from outside by $.fn.selectonic.defaults.

Callbacks (Events)

Callback functions except create and destroy may get arguments:

event — event object from mouse or keyboard handlers.
ui — object that contains properties with HTML elements:
- target — link to an element, that has clicked or chosen by keyboard.
- focus — link to an element that has been a target previously;
- items — jquery collection of changed items – it could differ from event to event. Look at a table below.

Callback functions in order which they are called and with arguments which they receives:

Callback	event	ui.target	ui.focus	ui.items
create — calls after initialization.	—	—	—	—
before — calls in every work cycle before any changes.	YES	if exists	if exists	—
unselect — one or more elements has been unselected.	YES	if exists	if exists	jquery collection of unselected elements
select — when one or more elements has been selected.	YES	YES	if exists	jquery collection of selected elements
unselectAll — when all elements in the list has been unselected.	YES	if exists	if exists	jquery collection of unselected elements
focusLost — when the focus of the list is lost.	YES	—	YES. Focus will be removed after this callback.	—
stop — calls in the end of every work cycle.	YES	if exists	if exists – but it will already be a new focus.	all changed items (if they were)
destroy — calls before plugin's destroy.	—	—	—	—

Link this inside callbacks refers to list's initial element wrapped in jQuery, so you may call any method inside callbacks functions like this.selectonic("disable");.

Methods

Calling a method:

$(elem).selectonic("getSelected");

Method	Description
isEnabled	Returns `true` if list is in enabled state.
blur	Clears focus and selection of the list, if it's permitted by list's options.
getSelected	Gets a jQuery collection of selected elements.
getSelectedId	Gets an array of id's of selected elements.
scroll	If a list has focused element and list is scrollable, it will recalculate list's scroll position in a way that focused element will be in a viewport.
disable	Disables selectable list, but keeps data and saves it state.
enable	Turns on disabled plugin.
refresh	Refreshes plugin data. That is necessary when some items in a list has been removed.
destroy	Detaches handlers, clears data and removes HTML-classes.

option

Gets or sets one or more options.

Getter:

var mouseMode = $(elem).selectonic("option", "mouseMode");

…or you can get whole options object:

var options = $(elem).selectonic("option");

Setter:

$(elem).selectonic("option", "mouseMode", "toggle");

or

$(elem).selectonic("option", {
    loop: true,
    mouseMode: "mouseup"
});

cancel

Cancel current changes in a list or prevent it, if called in before callback. Method can be called only inside callback function:

elem.selectonic({
    stop: function(event, ui) {
        if( condition ) {
            this.selectonic("cancel"); // inside callback
        }
    }
});

focus

Gets focused element or null or sets new focused element.

Getter:

$(elem).selectonic("focus"); //returns focus or null if there is no one

Setter:

$(elem).selectonic("focus", elem); //if elem is a list's item it will be focused

$(elem).selectonic("focus", 0); //first element in the list

select

If in any scenario you need auto-select items (select first item at the beginning) then you need pass element to select method:

$(elem).selectonic("select", $(".someElements"));

or selector:

$(elem).selectonic("select", ":even");

$(elem).selectonic("select", "li:eq(3)");

You also could select an item by passing its number:

$(elem).selectonic("select", 0);

select method only selects passed items but doesn't clear selection from others items, if they are. Method doesn't change focused element.

unselect

Unselects passed items or all items if no one has been passed:

$(elem).selectonic("unselect", $(".someElements")); //clear selection for these items
$(elem).selectonic("unselect"); //clear selection for all items

Method doesn't change focused element.
