The Form Element Repeater jQuery plugin allows the user to dynamically add and remove repeatable groups of form fields that are easy to style and customize.

Basic usage:

1. Create a group of form fields that will be repeatable. Available HTML data attributes;

  • data-pattern-text: text pattern
  • data-pattern-id: the ID of each each form field
  • data-pattern-name: name pattern
<div class="example">
  <div class="r-group">
      <label for="demo_0_0" data-pattern-text="Demo Name +=1:">Demo Name 1:</label>
      <input type="text" name="demo[0][name]" id="demo_0_name" data-pattern-name="demo[++][name]" data-pattern-id="demo_++_name" />
      <label for="demo_0_0" data-pattern-text="Demo Type +=1:">Demo Type 1:</label>
      <input type="text" name="demo[0][type]" id="demo_0_type" data-pattern-name="demo[++][type]" data-pattern-id="demo_++_type" />
      <!-- Add a remove button for the item. If one didn't exist, it would be added to overall group -->
      <button type="button" class="r-btnRemove">Remove -</button>

2. Create an 'Add' button next to the form fields.

<button type="button" class="r-btnAdd">Add +</button>

3. Include the necessar JavaScript files at the bottom of the web page.

<script src="" 
<script src="jquery.form-repeater.js"></script>

4. Activate the form repeater plugin with default settings. Possible parameters:

  • options: an object of possible plugin options.
  • data: an array of data objects containing form fields to clone.
$('#example1').repeater(options, data);

5. You can also clone the form fields defined in the data array on init.

$('#example').repeater(options, [

6. All possible options (with default values) to customize the form repeater.


  // default CSS selectors
  groupClass: 'r-group',
  btnAddClass: 'r-btnAdd',
  btnRemoveClass: 'r-btnRemove',

  // min/max amount of items
  minItems: 1,
  maxItems: 0,

  // the starting index of your array.
  startingIndex: 0,
  reindexOnDelete: true,

  // shows min items on load
  showMinItemsOnLoad: false,

  // append, prepend, insertAfterLast 
  repeatMode: 'insertAfterLast', 

  // 'slide' or 'fade'
  animation: null,

  // animation speed
