Responsive, Draggable, Filterable Grid Layout – muuri

Preview:

Description:

muuri is a versatile JavaScript library that helps you create responsive, draggable, filterable, searchable grid layouts with smooth web animations.

Install it via package managers:

# Yarn
yarn add muuri
# NPM
$ npm install muuri
# Bower
$ bower install muuri

Basic usage:

1. Include the main JavaScript file ‘muuri.js’ on the webpage.

<script src="muuri.min.js"></script>

2. Include the Web Animations Polyfill if needed.

<script src="https://cdn.jsdelivr.net/npm/w[email protected]/web-animations.min.js"></script>

3. Add your own grid items to the layout.

<div class="grid">
  <div class="item">
    <div class="item-content">
      Item 1
    </div>
  </div>
  <div class="item">
    <div class="item-content">
      Item 2
    </div>
  </div>
  <div class="item">
    <div class="item-content">
      Item 3
    </div>
  </div>
  ...
</div>

4. Initialize the grid layout:

var grid = new Muuri('.grid');

5. Apply your own CSS styles to the layout & grid items:

.grid {
  position: relative;
}
.item {
  display: block;
  position: absolute;
  width: 100px;
  height: 100px;
  margin: 5px;
  z-index: 1;
  background: #000;
  color: #fff;
}
.item.muuri-item-dragging {
  z-index: 3;
}
.item.muuri-item-releasing {
  z-index: 2;
}
.item.muuri-item-hidden {
  z-index: 0;
}
.item-content {
  position: relative;
  width: 100%;
  height: 100%;
}

6. Config the grid layout with the following options.

var grid = new Muuri('.grid',{
    // Initial item elements
    items: '*',
    // Default show animation
    showDuration: 300,
    showEasing: 'ease',
    // Default hide animation
    hideDuration: 300,
    hideEasing: 'ease',
    // Item's visible/hidden state styles
    visibleStyles: {
      opacity: '1',
      transform: 'scale(1)'
    },
    hiddenStyles: {
      opacity: '0',
      transform: 'scale(0.5)'
    },
    // Layout
    layout: {
      fillGaps: false,
      horizontal: false,
      alignRight: false,
      alignBottom: false,
      rounding: false
    },
    layoutOnResize: 150,
    layoutOnInit: true,
    layoutDuration: 300,
    layoutEasing: 'ease',
    /* e.g.
    sortData: {
      foo: function (item, element) {
        return parseFloat(element.getAttribute('data-foo'));
      },
      bar: function (item, element) {
        return element.getAttribute('data-bar').toUpperCase();
      },
    },
    */
    sortData: null,
    // Drag & Drop Options
    dragEnabled: false,
    dragContainer: null,
    dragHandle: null,
    dragStartPredicate: {
      distance: 0,
      delay: 0
    },
    dragAxis: 'xy', // 'x', 'y'
    dragSort: true,
    dragSortHeuristics: {
      sortInterval: 100,
      minDragDistance: 10,
      minBounceBackAngle: 1
    },
    dragSortPredicate: {
      threshold: 50,
      action: 'move',
      migrateAction: 'move'
    },
    dragRelease: {
      duration: 300,
      easing: 'ease',
      useDragContainer: true
    },
    dragCssProps: {
      touchAction: 'none',
      userSelect: 'none',
      userDrag: 'none',
      tapHighlightColor: 'rgba(0, 0, 0, 0)',
      touchCallout: 'none',
      contentZooming: 'none'
    },
    dragPlaceholder: {
      enabled: false,
      createElement: null,
      onCreate: null,
      onRemove: null
    },
    dragAutoScroll: {
      targets: [],
      handle: null,
      threshold: 50,
      safeZone: 0.2,
      speed: Muuri.AutoScroller.smoothSpeed(1000, 2000, 2500),
      sortDuringScroll: true,
      smoothStop: false,
      onStart: null,
      onStop: null
    },
    // Classnames
    containerClass: 'muuri',
    itemClass: 'muuri-item',
    itemVisibleClass: 'muuri-item-shown',
    itemHiddenClass: 'muuri-item-hidden',
    itemPositioningClass: 'muuri-item-positioning',
    itemDraggingClass: 'muuri-item-dragging',
    itemReleasingClass: 'muuri-item-releasing',
    itemPlaceholderClass: 'muuri-item-placeholder'
});

7. You can also set options globally.

Muuri.defaultOptions.showDuration = 400;
Muuri.defaultOptions.dragSortPredicate.action = 'swap';
