|
* 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.

|
* CSS required to position all widgets in their respective columns
|
|
* 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
|
|

|
|
* 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 {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.
|

|
|
* 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.
|
|
* @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]`
