Repository files' structure

Options

• selector (required) - element type used inside of picker (html tag like li / span / i, checkbox / radio - for input type checkbox / radio)
• inputName - name of input where checked values will be stored. Plugin will create new one if input does not exist on the page (only for non checkbox / radio elements). If inputName doesn't specified, picker container's id will be used for input name. For avoiding conflict strongly recommend to provide valid, unique name.
• valueSource - source from where plugin should get value for element, possible values are: index, text, data-* attribute, default value is index (only for non checkbox / radio elements)
• prePopulate - string or array of element(s) which should be selected by default (useful for edit mode), could be index, data-* or text of elements', must match to valueSource
• disabled - string or array of element(s) which should be disabled (useful for edit mode), could be index, data-* or text of elements', must match to valueSource. Also its possible to disable elements using checkboxes' and radiobuttons' disabled attribute, like <input type="checkbox" disabled="true">
• isSingle - allows user to select only one option from picker (like input[type="radio"] in pure html forms) default value is false (only for non checkbox / radio elements)
• cssOptions - object with options described below:

Option	Default value	Description
vertical	false	picker's horizontal / vertical position
quadratic	false	by default picker is rounded, specify this option true to make it square
size	"medium"	picker's size, available values are "small", "medium", "large"
picker	empty object	css styles (key / value js object) will be assigned to the picker
element	empty object	css styles (key / value js object) will be assigned to the elements inside of picker

Usage with checkboxes and radiobuttons.

In case when html tags like li or span used in multipicker, it will store values in hidden input, which will be a string separated by commas, like this "Su, Mo, Fr, Sa". You should split this string on the server (on client in some cases), to store these values in database or make it possible to use them in picker in the future (for example when user wants to edit his choices).

In case when you are using checkboxes or radiobuttons, selected items will check checkbox/radiobutton in standart html way. Picker will modify your markup, and you will get html code like these:

multiple items for checkboxes

<div id="programming-languages">
    <input type="checkbox" name="lang" value="C" checked="true">
    <input type="checkbox" name="lang" value="JS">
    <input type="checkbox" name="lang" value="Swift" checked="true">
    <input type="checkbox" name="lang" value="Java">
    <input type="checkbox" name="lang" value="C#">
    <input type="checkbox" name="lang" value="C++" checked="true" >
    <input type="checkbox" name="lang" value="PHP">
</div>

or single selected item for radiobuttons

<div id="programming-languages">
    <input type="radio" name="lang" value="C">
    <input type="radio" name="lang" value="JS">
    <input type="radio" name="lang" value="Swift" checked="true">
    <input type="radio" name="lang" value="Java">
    <input type="radio" name="lang" value="C#">
    <input type="radio" name="lang" value="C++">
    <input type="radio" name="lang" value="PHP">
</div>

You can access selected values in standart way as you would do with checkboxes and radiobuttons if plugin wouldn't been used.

More Examples:

Set isSingle: true to make only one element selectable like radiobuttons in html.

$("#days").multiPicker({
    selector: "li",
    isSingle: true
});

Specify prePopulate array and valueSource options to get some options selected by default

$("#days").multiPicker({
    selector : "li",
    prePopulate : ["Tu", "Fr"],
    valueSource : "data-value"
});

To make your picker vertical just use cssOptions vertical : true property

<div id="days-vertical">
    <span>Su</span>
    <span>Mo</span>
    <span>Tu</span>
    <span>We</span>
    <span>Th</span>
    <span>Fr</span>
    <span>Sa</span>
</div>

$("#days-vertical").multiPicker({
    selector   : "span",
    cssOptions : {
        vertical: true
    }
});

Using radiobuttons

<div id="languages">
	<input type="radio" name="language" value="EN">
	<input type="radio" name="language" value="HY">
	<input type="radio" name="language" value="RU">
	<input type="radio" name="language" value="EN">
	<input type="radio" name="language" value="JP">
	<input type="radio" name="language" value="DE">
	<input type="radio" name="language" value="FR">
</div>

$("#languages").multiPicker({ selector : "radio" });

Using checkboxes

With vertical, quadratic and prepopulated options:

<div id="programming-languages">
	<input type="checkbox" name="lang" value="C">
	<input type="checkbox" name="lang" value="JS">
	<input type="checkbox" name="lang" value="Swift">
	<input type="checkbox" name="lang" value="Java">
	<input type="checkbox" name="lang" value="C#">
	<input type="checkbox" name="lang" value="C++">
	<input type="checkbox" name="lang" value="PHP">
</div>

$("#programming-languages").multiPicker({
	selector	: "checkbox",
	prePopulate : ["C", "C++"],
	cssOptions  : {
		quadratic : true,
		vertical  : true
	}
});

Design customisation

Plugin allows to use label tags to apply item text and keep input's value hidden from user. To apply custom design to multipicker you should use cssOptions (which is described in options section).

For Example, this picker's code

will be:

<div id="clubs">
	<label for="zero">JAN</label>
	<input id="zero" type="checkbox" name="club" value="0">
	<label for="one">FEB</label>
	<input id="one" type="checkbox" name="club" value="1">
	<label for="two">MAR</label>
	<input id="two" type="checkbox" name="club" value="2">
	<label for="three">APR</label>
	<input id="three"type="checkbox" name="club" value="3">
	<label for="four">MAY</label>
	<input id="four" type="checkbox" name="club" value="4">
	<label for="five">JUN</label>
	<input id="five" type="checkbox" name="club" value="5">
	<label for="six">JUL</label>
	<input id="six" type="checkbox" name="club" value="6">
	<label for="seven">AUG</label>
	<input id="seven" type="checkbox" name="club" value="7">
	<label for="eight">SEB</label>
	<input id="eight" type="checkbox" name="club" value="8">
	<label for="nine">OCT</label>
	<input id="nine" type="checkbox" name="club" value="9">
	<label for="ten">NOV</label>
	<input id="ten" type="checkbox" name="club" value="10">
	<label for="eleven">DEC</label>
	<input id="eleven" type="checkbox" name="club" value="11">
</div>

$("#clubs").multiPicker({
	selector    : "checkbox",
	prePopulate : "1",
	isSingle	: true,
	cssOptions 	: {
		size	  : "large",
		element	  : {
			"font-size"   : "11px",
			"color" 	  : "#3a3a3a",
			"font-weight" : "bold"
		},
		selected: {
			"border-color" : "#ff4c4c",
			"font-size"    : "14px"
		},
		picker: {
			"border-color" : "#ff4c4c"
		}
	}
});
