Welcome to MultiItem Documantation

Introduction

MultiItem is a jquery script that allows you to add multiple input or others with extensive customization

######Multi item wrapper

<div class="multi-element" data-input="items">

    <!-- 
        single elements here. Single element contains input sections with remove and sorting buttons. it may have multiple single elements 
    -->

</div>

######single element with remove button

<div class="single-element">
    <div>
        <input class="multi-input" data-key="first_name" name="items[0][first_name]" type="text" value="">
    </div>
    <div>
        <input class="multi-input" data-key="last_name" name="items[0][last_name]" type="text" value="">
    </div>
	
    <!-- remove item button -->
    <a href="javascript:;" class="btn btn-danger remove-item"><i class="fa fa-minus"></i></a>
</div>

######single element with sortable button.

<div class="single-element">
    <div>
        <input class="multi-input" data-key="first_name" name="items[0][first_name]" type="text" value="">
    </div>
    <div>
        <input class="multi-input" data-key="last_name" name="items[0][last_name]" type="text" value="">
    </div>
    
    <!-- remove item button -->
    <a href="javascript:;" class="btn btn-danger remove-item"><i class="fa fa-minus"></i></a>
    
    <!-- sorting item button -->
    <div class="move-place">
        <a class="move-up btn btn-danger" href="javascript:;"><i class="fa  fa-caret-up"></i></a>
        <a class="move-down btn btn-danger" href="javascript:;"><i class="fa fa-caret-down"></i></a>
    </div>
</div>

######So, your structure must be like this You are not allowed to break the format at all. but you can add classes to those tags to customize. Also in the input container div, you can add extra elements if you need.

<div class="multi-element" data-input="items">
	<div class="single-element">
		<div>
			<input class="multi-input" data-key="first_name" name="items[0][first_name]" type="text" value="">
		</div>
		<div>
			<input class="multi-input" data-key="last_name" name="items[0][last_name]" type="text" value="">
		</div>
		
		<!-- remove item button -->
		
		<!-- sorting item button -->
	</div>
	<div class="single-element">
		<div>
			<input class="multi-input" data-key="first_name" name="items[1][first_name]" type="text" value="">
		</div>
		<div>
			<input class="multi-input" data-key="last_name" name="items[1][last_name]" type="text" value="">
		</div>
		
		<!-- remove item button -->
		
		<!-- sorting item button -->
	</div>
</div>

######Dropdown field If you want to add a dropdown for a field the format wil be like it is given below

<div class="multi-element" data-input="items">
	<ul class="select-dropdown" style="display: none" id="floated-category">
		<li><input type="hidden" value="val1"><span>text 1</span></li>
		<li><input type="hidden" value="val2"><span>text 2</span></li>
	</ul>
	<ul class="select-dropdown" style="display: none" id="floated-subcategory">
		<li><input type="hidden" value="val1"><span>text 1</span></li>
		<li><input type="hidden" value="val2"><span>text 2</span></li>
	</ul>
	<div class="single-element">
		<div>
			<p class="single-unit form-control" data-id="floated-category">Select Option</p>
            		<input class="multi-input" data-key="name" name="items[0][name]" type="hidden" value="">
		</div>
		<div>
			<p class="single-unit form-control" data-id="floated-subcategory">Select Option</p>
            		<input class="multi-input" data-key="name" name="items[0][name]" type="hidden" value="">
		</div>
		
		<!-- remove item button -->
		
		<!-- sorting item button -->
	</div>
</div>

So, you can see, the id of first ul is placed in the first p tag's data-id, and second one is for second p. the input field is hidden there

######How to call Inlude the script <link rel="stylesheet" href="path/to/flie/style.css"> <script src="path/to/flie/multiitem.js"></script>

Call the script

$(document).ready(function () {
    $('.multi-element').multiitems({
        template: `
        <div>
            <input class="multi-input" data-key="first_name" name="" type="text" value="">
        </div>
        <div>
            <input class="multi-input" data-key="last_name" name="" type="text" value="">
        </div>
        `
    });
});

If you take a look carefully, we have not added single-element class or the remove or sort in the template. Those will be added automatically. We only added the core part with the input wrapper of the template also without the name of input field.

######Options

Option	Default Value	Required	Uses
template	null	Yes	This is the template that will be sorted, added or removed
removeButton	<a href="javascript:;" class="btn btn-danger remove-item"><i class="fa fa-minus"></i></a>	No	This is the html format of remove button that you can change
addButton	<a href="javascript:;" class="btn btn-info add-item mb-2" style="display: none"><i class="fa fa-plus"></i></a>	No	This is the html format of add button that you can change
moveButton	<div class="move-place"><a class="move-up btn btn-danger" href="javascript:;"><i class="fa fa-caret-up"></i></a><a class="move-down btn btn-danger" href="javascript:;"><i class="fa fa-caret-down"></i></a></div>	No	This is the html format of sorting buttons that you can change
removeButtonClass	remove-item	No	This is the handler of remove button
addButtonClass	add-item	No	This is the handler of add button
moveUpButtonClass	move-up	No	This is the handler of sorting up button
moveDownButtonClass	move-down	No	This is the handler of sorting down button
inverse	false	No	Make true if sorting is required
insertable	true	No	Make false if want to disable adding new element
removable	true	No	Make false if want to disable removing element
max	0	No	Integer value. If 0, you can add unlimited item or put a positive integer to limit the adding
externalFunction	null	No	call an external function on add item. value type must be array and maximum 2 items where first item is function name and second item (optional) is true/false. if true then multiitem returns the added dom

It works exactly like multiitem but some options are not available and the single-element section is little different as it doesn't have max, inversing, remove disabling and sortable option. Also custom dropdown option is unavailable. For everything else follow the doc of multi item

######Options that are not available moveUpButtonClass, moveDownButtonClass, inverse, insertable, removable, max, externalFunction
