* 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

* @param {Boolean} [options.autogenerate_stylesheet] If true, all the

* `[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.

* method or not when the plugin is instantiated.
* @param {Function} [options.serialize_params] Return the data you want

* @param {Object|Function} [options.draggable.ignore_dragging] Note that

* 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
* resizing.
* @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.
