+```
+
+Any line of the commit message cannot be longer 100 characters! This allows the message to be easier
+to read on github as well as in various git tools.
+
+### Type
+Must be one of the following:
+
+* **feat**: A new feature
+* **fix**: A bug fix
+* **docs**: Documentation only changes
+* **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing
+ semi-colons, etc)
+* **refactor**: A code change that neither fixes a bug or adds a feature
+* **perf**: A code change that improves performance
+* **test**: Adding missing tests
+* **chore**: Changes to the build process or auxiliary tools and libraries such as documentation
+ generation
+
+### Scope
+The scope could be anything specifying place of the commit change. For example `$location`,
+`$browser`, `$compile`, `$rootScope`, `ngHref`, `ngClick`, `ngView`, etc...
+
+### Subject
+The subject contains succinct description of the change:
+
+* use the imperative, present tense: "change" not "changed" nor "changes"
+* don't capitalize first letter
+* no dot (.) at the end
+
+### Body
+Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes"
+The body should include the motivation for the change and contrast this with previous behavior.
+
+### Footer
+The footer should contain any information about **Breaking Changes** and is also the place to
+reference GitHub issues that this commit **Closes**.
+
+**Breaking Changes** are detected as such if the Body contains a line starting with
+`BREAKING CHANGES:` The rest of the commit message is then used for this.
+
+A detailed explanation can be found in this [document](https://docs.google.com/document/d/1QrDFcIiPjSLDn3EL15IJygNPiHORgU1_OOAqWjiDU5Y/).

+
Grid with larger widgets swapping spots with smaller ones
+
This demo represents using the branch in swap mode. This works best with shift_larger_widgets_down set to "false". However, smaller widgets do
+ not displace larger ones.

+
Demo » Add widgets dynamically » gridster.js
+ Add widgets dynamically
+
+Create a grid adding widgets from an Array (not from HTML) using add_widget method. Widget position (col, row) not specified.

+ * @param {HTMLElement|String} [options.widget_selector] Define who will
+ * be the draggable widgets. Can be a CSS Selector String or a
+ * collection of HTMLElements
+ * @param {Array} [options.widget_margins] Margin between widgets.
+ * The first index for the horizontal margin (left, right) and
+ * the second for the vertical margin (top, bottom).
+ * @param {Array} [options.widget_base_dimensions] Base widget dimensions
+ * in pixels. The first index for the width and the second for the
+ * height.
+ * @param {Number} [options.extra_cols] Add more columns in addition to
+ * those that have been calculated.
+ * @param {Number} [options.extra_rows] Add more rows in addition to
+ * those that have been calculated.
+ * @param {Number} [options.min_cols] The minimum required columns.
+ * @param {Number} [options.max_cols] The maximum columns possible (set to null

+ * @param {Number} [options.min_rows] The minimum required rows.
+ * @param {Boolean} [options.autogenerate_stylesheet] If true, all the
+ * CSS required to position all widgets in their respective columns
+ * and rows will be generated automatically and injected to the
+ * `` of the document. You can set this to false, and write
+ * your own CSS targeting rows and cols via data-attributes like so:
+ * `[data-col="1"] { left: 10px; }`
+ * @param {Boolean} [options.avoid_overlapped_widgets] Avoid that widgets loaded
+ * from the DOM can be overlapped. It is helpful if the positions were
+ * bad stored in the database or if there was any conflict.
+ * @param {Boolean} [options.auto_init] Automatically call gridster init
+ * method or not when the plugin is instantiated.
+ * @param {Function} [options.serialize_params] Return the data you want
+ * for each widget in the serialization. Two arguments are passed:
+ * `$w`: the jQuery wrapped HTMLElement, and `wgd`: the grid
+ * coords object (`col`, `row`, `size_x`, `size_y`).
+ * @param {Boolean} [options.shift_larger_widgets_down] Determines if how widgets get pushes
+ * out of the way of the player. If set to false smaller widgets will not move larger
+ * widgets out of their way . Defaults to true.
+ * @param {Boolean} [options.shift_widgets_up] Determines if the player will automatically
+ * condense the grid and not allow a widget to have space above it. Defaults to true.
+ * @param {Function} [options.show_element] Makes the given element visible. Two arguments are passed:
+ * `$el`: the jQuery wrapped HTMLElement, and `callback`: a function that is executed
+ * after the element is made visible. The callback parameter is optional.
+ * @param {Function} [options.hide_element] Hides the given element. Two arguments are passed:
+ * `$el`: the jQuery wrapped HTMLElement, and `callback`: a function that is executed
+ * after the element is hidden. The callback parameter is optional.
+ * @param {Object} [options.collision] An Object with all options for
+ * Collision class you want to overwrite. See Collision docs for
+ * more info.
+ * @param {Boolean} [options.collision.wait_for_mouseup] Default is false.
+ * If true then it will not move colliding widgets during drag, but only on
+ * mouseup.
+ * @param {Object} [options.draggable] An Object with all options for
+ * Draggable class you want to overwrite. See Draggable docs for more info.
+ * @param {Object|Function} [options.draggable.ignore_dragging] Note that
+ * if you use a Function, and resize is enabled, you should ignore the
+ * resize handlers manually (options.resize.handle_class).

+ * @param {Array} [options.resize.axes] Axes in which widgets can be
+ * resized. Possible values: ['x', 'y', 'both'].
+ * @param {String} [options.resize.handle_append_to] Set a valid CSS
+ * selector to append resize handles to.
+ * @param {String} [options.resize.handle_class] CSS class name used
+ * by resize handles.
+ * @param {Array} [options.resize.max_size] Limit widget dimensions
+ * when resizing. Array values should be integers:
+ * `[max_cols_occupied, max_rows_occupied]`
+ * @param {Array} [options.resize.min_size] Limit widget dimensions
+ * when resizing. Array values should be integers:
+ * `[min_cols_occupied, min_rows_occupied]`
+ * @param {Function} [options.resize.start] Function executed
+ * when resizing starts.
+ * @param {Function} [options.resize.resize] Function executed

+ * @param {HTMLElement} el The HTMLelement that contains all the widgets.
+ * @param {Object} [options] An Object with all options you want to
+ * overwrite:
+ * @param {HTMLElement|String} [options.widget_selector] Define who will
+ * be the draggable widgets. Can be a CSS Selector String or a
+ * collection of HTMLElements
+ * @param {Array} [options.widget_margins] Margin between widgets.
+ * The first index for the horizontal margin (left, right) and
+ * the second for the vertical margin (top, bottom).
+ * @param {Array} [options.widget_base_dimensions] Base widget dimensions
+ * in pixels. The first index for the width and the second for the
+ * height.
+ * @param {Number} [options.extra_cols] Add more columns in addition to
+ * those that have been calculated.
+ * @param {Number} [options.extra_rows] Add more rows in addition to
+ * those that have been calculated.
+ * @param {Number} [options.min_cols] The minimum required columns.
+ * @param {Number} [options.max_cols] The maximum columns possible (set to null

+ * @param {Number} [options.min_rows] The minimum required rows.
+ * @param {Boolean} [options.autogenerate_stylesheet] If true, all the
+ * CSS required to position all widgets in their respective columns
+ * and rows will be generated automatically and injected to the
+ * `` of the document. You can set this to false, and write
+ * your own CSS targeting rows and cols via data-attributes like so:
+ * `[data-col="1"] { left: 10px; }`
+ * @param {Boolean} [options.avoid_overlapped_widgets] Avoid that widgets loaded
+ * from the DOM can be overlapped. It is helpful if the positions were
+ * bad stored in the database or if there was any conflict.
+ * @param {Boolean} [options.auto_init] Automatically call gridster init
+ * method or not when the plugin is instantiated.
+ * @param {Function} [options.serialize_params] Return the data you want
+ * for each widget in the serialization. Two arguments are passed:
+ * `$w`: the jQuery wrapped HTMLElement, and `wgd`: the grid
+ * coords object (`col`, `row`, `size_x`, `size_y`).
+ * @param {Boolean} [options.shift_larger_widgets_down] Determines if how widgets get pushes
+ * out of the way of the player. If set to false smaller widgets will not move larger
+ * widgets out of their way . Defaults to true.
+ * @param {Boolean} [options.shift_widgets_up] Determines if the player will automatically
+ * condense the grid and not allow a widget to have space above it. Defaults to true.
+ * @param {Function} [options.show_element] Makes the given element visible. Two arguments are passed:
+ * `$el`: the jQuery wrapped HTMLElement, and `callback`: a function that is executed
+ * after the element is made visible. The callback parameter is optional.

+ * `$el`: the jQuery wrapped HTMLElement, and `callback`: a function that is executed
+ * after the element is hidden. The callback parameter is optional.
+ * @param {Object} [options.collision] An Object with all options for
+ * Collision class you want to overwrite. See Collision docs for
+ * more info.
+ * @param {Boolean} [options.collision.wait_for_mouseup] Default is false.
+ * If true then it will not move colliding widgets during drag, but only on
+ * mouseup.
+ * @param {Object} [options.draggable] An Object with all options for
+ * Draggable class you want to overwrite. See Draggable docs for more info.
+ * @param {Object|Function} [options.draggable.ignore_dragging] Note that
+ * if you use a Function, and resize is enabled, you should ignore the
+ * resize handlers manually (options.resize.handle_class).
+ * @param {Object} [options.resize] An Object with resize config options.
+ * @param {Boolean} [options.resize.enabled] Set to true to enable

+ * @param {Array} [options.resize.axes] Axes in which widgets can be
+ * resized. Possible values: ['x', 'y', 'both'].
+ * @param {String} [options.resize.handle_append_to] Set a valid CSS
+ * selector to append resize handles to.
+ * @param {String} [options.resize.handle_class] CSS class name used
+ * by resize handles.
+ * @param {Array} [options.resize.max_size] Limit widget dimensions
+ * when resizing. Array values should be integers:
+ * `[max_cols_occupied, max_rows_occupied]`
+ * @param {Array} [options.resize.min_size] Limit widget dimensions
+ * when resizing. Array values should be integers:
+ * `[min_cols_occupied, min_rows_occupied]`
+ * @param {Function} [options.resize.start] Function executed
+ * when resizing starts.
+ * @param {Function} [options.resize.resize] Function executed
+ * during the resizing.

+ * @param {HTMLElement} el The HTMLelement that contains all the widgets.
+ * @param {Object} [options] An Object with all options you want to
+ * overwrite:
+ * @param {HTMLElement|String} [options.widget_selector] Define who will
+ * be the draggable widgets. Can be a CSS Selector String or a
+ * collection of HTMLElements
+ * @param {Array} [options.widget_margins] Margin between widgets.
+ * The first index for the horizontal margin (left, right) and
+ * the second for the vertical margin (top, bottom).
+ * @param {Array} [options.widget_base_dimensions] Base widget dimensions
+ * in pixels. The first index for the width and the second for the
+ * height.
+ * @param {Number} [options.extra_cols] Add more columns in addition to
+ * those that have been calculated.
+ * @param {Number} [options.extra_rows] Add more rows in addition to
+ * those that have been calculated.
+ * @param {Number} [options.min_cols] The minimum required columns.
+ * @param {Number} [options.max_cols] The maximum columns possible (set to null
+ * for no maximum).
+ * @param {Number} [options.min_rows] The minimum required rows.
+ * @param {Boolean} [options.autogenerate_stylesheet] If true, all the
+ * CSS required to position all widgets in their respective columns
+ * and rows will be generated automatically and injected to the
+ * `` of the document. You can set this to false, and write
+ * your own CSS targeting rows and cols via data-attributes like so:
+ * `[data-col="1"] { left: 10px; }`
+ * @param {Boolean} [options.avoid_overlapped_widgets] Avoid that widgets loaded
+ * from the DOM can be overlapped. It is helpful if the positions were
+ * bad stored in the database or if there was any conflict.
+ * @param {Boolean} [options.auto_init] Automatically call gridster init
+ * method or not when the plugin is instantiated.
+ * @param {Function} [options.serialize_params] Return the data you want
+ * for each widget in the serialization. Two arguments are passed:
+ * `$w`: the jQuery wrapped HTMLElement, and `wgd`: the grid
+ * coords object (`col`, `row`, `size_x`, `size_y`).
+ * @param {Boolean} [options.shift_larger_widgets_down] Determines if how widgets get pushes
+ * out of the way of the player. If set to false smaller widgets will not move larger
+ * widgets out of their way . Defaults to true.
+ * @param {Boolean} [options.shift_widgets_up] Determines if the player will automatically
+ * condense the grid and not allow a widget to have space above it. Defaults to true.
+ * @param {Function} [options.show_element] Makes the given element visible. Two arguments are passed:
+ * `$el`: the jQuery wrapped HTMLElement, and `callback`: a function that is executed
+ * after the element is made visible. The callback parameter is optional.
+ * @param {Function} [options.hide_element] Hides the given element. Two arguments are passed:
+ * `$el`: the jQuery wrapped HTMLElement, and `callback`: a function that is executed
+ * after the element is hidden. The callback parameter is optional.

+ * Collision class you want to overwrite. See Collision docs for
+ * more info.
+ * @param {Boolean} [options.collision.wait_for_mouseup] Default is false.
+ * If true then it will not move colliding widgets during drag, but only on
+ * mouseup.
+ * @param {Object} [options.draggable] An Object with all options for
+ * Draggable class you want to overwrite. See Draggable docs for more info.
+ * @param {Object|Function} [options.draggable.ignore_dragging] Note that
+ * if you use a Function, and resize is enabled, you should ignore the
+ * resize handlers manually (options.resize.handle_class).

+ * @param {String} [options.resize.handle_append_to] Set a valid CSS
+ * selector to append resize handles to.
+ * @param {String} [options.resize.handle_class] CSS class name used
+ * by resize handles.
+ * @param {Array} [options.resize.max_size] Limit widget dimensions
+ * when resizing. Array values should be integers:
+ * `[max_cols_occupied, max_rows_occupied]`
+ * @param {Array} [options.resize.min_size] Limit widget dimensions
+ * when resizing. Array values should be integers:
+ * `[min_cols_occupied, min_rows_occupied]`
+ * @param {Function} [options.resize.start] Function executed
+ * when resizing starts.
+ * @param {Function} [options.resize.resize] Function executed
