- * 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

- * and rows will be generated automatically and injected to the
- * `<head>` 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

- * @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

- * @param {Object} [options.collision] An Object with all options for
- * Collision class you want to overwrite. See Collision docs for
- * more info.
- * @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
- * resizing.

- * 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
