Best Grid Layout Plugins

Basic Usage (Vanilla JS Version):

1. Install & Download the package.

# Yarn
$ yarn add gridstack

# NPM
$ npm install gridstack --save

2. Include the necessary JavaScript and CSS files on the page.

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/gridstack.min.css" />
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/gridstack.all.js"></script>

3. Insert optional grid items to the Grid Stack container and pass the options via data-option attributes as follows:

<div class="grid-stack">
  <div class="grid-stack-item">
    <div class="grid-stack-item-content">Item 1</div>
  </div>
  <div class="grid-stack-item" data-gs-width="2">
    <div class="grid-stack-item-content">Item 2 wider</div>
  </div>
</div>

Basic Usage (jQuery Version):

1. Include jQuery library and other required resources in the the document.

jQuery
jQuery UI
jQuery UI Touch Punch: for touch support (OPTIONAL)
gridstack.poly.js: for IE and older browsers (OPTIONAL)

<!-- Local -->
<link href="/path/to/gridstack.css" rel="stylesheet" />
<!-- Or From A CDN -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/gridstack.min.css" />

2. Include the jQuery Gridstack.js plugin and other required resources at the end of the document.

<!-- Dependencies -->
<script src="/path/to/cdn/jquery.min.js"></script>
<script src="/path/to/cdn/jquery-ui.min.js"></script>
<script src="/path/to/cdn/jquery.ui.touch-punch.min.js"></script>

<!-- Or from a CDN -->
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/gridstack.all.js"></script>
<!-- Polyfill for old IE -->
<script src="gridstack.poly.js"></script>

3. Create a sample draggable grid layout as follows.

gs-animate: turns animation on (for grid)
gs-column: amount of columns (for grid)
gs-max-row: maximum rows amount, defaults to 0 (for grid)
gs-current-height: current rows amount (for grid)
gs-id: unique ID (for item)
gs-x, data-gs-y: element position (for item)
gs-width, data-gs-height: element size (for item)
gs-max-width, gs-min-width, gs-max-height, gs-min-height: element constraints (for item)
gs-no-resize: disable element resizing (for item)
gs-no-move: disable element moving (for item)
gs-auto-position: tells to ignore data-gs-x and data-gs-y attributes and to place element to the first available position (for item)
gs-locked: the widget will be locked. It means another widgets couldn't move it during dragging or resizing. The widget is still can be dragged or resized. You need to add data-gs-no-resize and data-gs-no-move attributes to completely lock the widget (for item)
gs-resize-handles: resize handles (for item)
gs-static-grid: whether to make grid static

<div class="grid-stack" data-gs-width="12">
  <div class="grid-stack-item" gs-x="0" data-gs-y="0" gs-width="4" gs-height="2">

Changelog:

v4.2.1 (2021-04-19)

fixed: JQ nested grid drag fix broken in 4.0.3 (but much older underlying issue)
fixed: item gs-x:0 not animating fix
fixed: resize-scroll issue when grid is not at top of page. Thanks @Manfred-on-github
fixed: fix sizing from top/left sides

v4.2.0 (2021-04-12)

fixed: scrollbar fix broken in 4.x
fixed: addWidget() while in 1 column now remembers original wanted width
added: addWidget() now supports nested grids like init/addGrid() does

v4.1.0 (2021-04-08)

fixed Can't easily drag widgets below widgets on the bottom border of a grid
when dragging an item at the bottom below others to make it easier to insert below.
more fix for drag between 2 grids with row / maxRow broken in 4.x
fix export symbols .d.ts for gridstack-h5.js | gridstack-jq.js | gridstack-static.js
fix correct info for using JQ version and ES6 (tested in Angular app)

v4.0.3 (2021-03-29)

fix load after init() broken in 4.x
fix drag between 2 grids with row / maxRow broken in 4.x
fix drag edge case in/out single grid without acceptWidgets fix broken in 4.x

v4.0.2 (2021-03-28)

fix: {handles:'w/sw'} work again in 4.x
fix: enableMove(T/F) not working correctly
fix helper: myFunction now working for H5 case for dragInOptions & setupDragIn()
fix: prevent addGrid() from creating nested div grid if container already is a '.grid-stack' div

v4.0.1 (2021-03-21)

fix JQ resize broken
fix serialization of nested grid

v4.0.0 (2021-03-20)

add drag | resize events while dragging
add GridStack.setupDragIn() so user can update external draggable after the grid has been created
fixed bugs

v3.3.0 (2021-02-03)

big re-write on how cellHeight() works. you can now call it at any time (not just grid init options) including switching to 'auto' or other modes on the fly.
fix cellHeight:auto now keeps cell square as window resizes (regressing from 2.x TS conversion). Utils.throttle() works better too (guaranteed to be called last event)
new cellHeight:initial which makes the cell squares initially, but doesn't change as windows resizes (better performance)
new grid option cellHeightThrottle (100ms) to control throttle of auto sizing triggers
fixed: height too small with cellHeight:auto loading in 1 column. Now detect we load at 1 column and size accordingly (default 'auto' could make big 700x700 cells, so explicit px might still be wanted)
fixed: loading nested into small size and sizing back up
fixed: nested grid resizing fix
fixed: H5 resize from left side can move item right

v3.2.0 (2021-01-26)

fix website & lib works on mobile. We now compile the latest v1.0.8 jquery.ui.touch-punch into the JQ version (only 2k) so mobile devices (android, iphone, ipad, ms surface, etc...) are supported out of the box. HTML5 version will require re-write to plain mousemove & mobile touchmove instead of drag events in a future release.
small optimizations (create placeholder content on the fly, moved more DD code into draggable class)

v3.1.5 (2021-01-24)

fix column: N option now sets CSS class
fix don't allow drop when grid is full
fix easier to drag out/in from below
fix cellHeight() not updating CSS correctly
fix H5 draggable by actual div handle rather than entire item (let content respond to drag as well)

v3.1.4 (2021-01-12)

fix no-drop cursor on windows when dragging within a default grid (no external drag in)
fix Safari H5 delay when dropping items

v3.1.3 (2021-01-03)

bugfixes

v3.1.2 (2020-12-08)

fix dragging into a fixed row grid works better (check if it will fit, else try to append, else won't insert)
possible BREAK (unlikely you use engine directly)
engine constructor takes Options struct rather than spelling arguments (easier to extend/use)
canBePlacedWithRespectToHeight() -> willItFit() like grid method
fix maxW does not work as intended with resizable handle "w"
fix support all options for new dragged in widgets (read all gs-xyz attributes)
fix dragging any grid item content works
fix web-component fixes & grid with 0 size initially. (edited)

v3.1.0 (2020-12-05)

add new addGrid(parent, opts) to create a grid and load children instead of init() + load(), which is used by load() to supports nested grids creation.
save() will now work on nested grids, recursively saving info. added flag to also allow saving the current grid options + children (needed for nested grids) so you can now call new adddGrid() to re-create everything from JSON.
fixed: don't call movable()/resizable() on locked items error.
fixed: force typescript 3.6 as 3.7+ has breaking change forcing apps to be at least 3.7 (we only used one tiny feature in newest TS, not worth the incompatibility).

v3.0.0 (2020-11-30)

Native HTML5 drag&drop plugin included
Fix placeholder not having custom GridStackOptions.itemClass. thanks @pablosichert
Fix dragging between 2 grids and back (regression in 2.0.1)
Fix load() into 1 column mode doesn't resize back to 12 correctly
Fix update(el, opts) re-write to take all GridStackWidget options (not just x,y,width,height) and do everything efficiently.
Hiding locked(), move(), resize(), minWidth(), etc... as they just simply call update() which does all the constrain now as well!
Del ddPlugin grid option as we only have one drag&drop plugin at runtime, which is defined by the include you use (HTML5 vs jquery vs none)
Change attribute data-gs-min-width is now gs-min-w. We removed 'data-' from all attributes, and shorten 'width|height' to just 'w|h' to require less typing and more efficient (2k saved in .js alone!)
Also GridStackWidget used in most API width|height|minWidth|minHeight|maxWidth|maxHeight are now shorter w|h|minW|minH|maxW|maxH

v2.2.0 (2020-11-08)

add margin option now support multi values CSS format '5px 10px 0 20px' or '5em 10em'
add data-gs-static-grid attribute
fix class="ui-draggable-disabled ui-resizable-disabled" have been added back to static grid items, so existing CSS rule to style continue working
fix getting DOM element by id with number works (api that uses GridStackElement handle more string formats)
fix setting marginTop (or any 4 sides) to cause resize to break

v2.1.0 (2020-10-29)

fix grid static: true to no longer add any drag&drop (even disabled) which should speed things up, and setStatic(T/F) will now correctly add it back/delete for items that need it only.
Also fixed JQ draggable warning if not initialized first
add addWidget(opt) now handles just passing a GridStackWidget which creates the default divs, simplifying your code. Old API still supported.
add save(saveContent = true) now lets you optionally save the HTML content in the node property, with load() restoring it
add GridStackWidget.content now lets you add any HTML content when calling load()/save() or addWidget()
add ColumnOptions to column(n, options) for multiple re-layout options, including 'none' that will preserve the x and width, until out of bound/overlap

v2.0.2 (2020-10-06)

fix animate to not re-create CSS style each time (should be faster too) and made it default now since so much nicer. pass {animate: false} grid options if you want instant again
fix resizable: { handles: ...} forcing alwaysShowResizeHandle behavior

v2.0.1 (2020-09-27)

lots of bugs fixes

v2.0.0 (2020-09-05)

re-write to native Typescript, removing all JQuery from main code and API (drag&drop plugin still using jqueryui for now)
add getGridItems() to return list of HTML grid items
add {dragIn | dragInOptions} grid attributes to handle external drag&drop items
add save() and load() to serialize grids from JSON, saving all attributes (not just w,h,x,y)
add margin to replace verticalMargin which affects both dimensions in code, rather than one in code the other in CSS.
You can now have perfect square cells (default)
fix #1299 many columns round-off error
fix #1102 loose functionality when they are moved to a new grid
add optional params to removeWidget() to have quiet mode (no callbacks)

v1.2.1 (2020-09-05)

Enable the UMD behavior for bundlers compatibility

v1.2.0 (2020-05-18)

fix domAttr is not defined
adds styleInHead option to allow for selecting older behavior (adding STYLE element to HEAD element instead of parentNode)
update jquery to v3.5.1

v1.1.2 (2020-05-18)

fixed: staticGrid no longer disable oneColumnMode
fixed: options broken with ember hash helper - thanks @btecu
fixed: don't remove item from another grid
fixed: init() clones passed options so second doesn't affect first one
fixed: addWidget() ignores data attributes

v1.1.1 (2020-04-13)

jQuery was removed from the API and dependencies (initialize differently, and methods take/return GridStack or HTMLElement instead of JQuery).
Updated Doc accordingly.

v0.6.4 (2020-02-18)

optimized change callback to save original x,y,w,h values and only call those that changed
more bugs fixed
