Use the same element as the original widget for the preview holder.
Using a <li> can cause a list item bullet to be displayed when widgets
are not necessarily <li> elements.
After beginning a drag, if the mouse button is released outside of the
screen, and if a subsequent drag operation is begun on another widget
(while the previous widget still follows the mouse around), Draggable
will trigger a new drag start event, causing Gridster to leave the
current widget + its preview holder aside and start dragging the new
widget. This will lead to an orphan preview holder to be left on the
screen.
A quick solution is to ignore drag start without receiving a drag stop.
Check to avoid generation of duplicated stylesheet-tags shouldn't have
been removed from Gridster. It's useful when calling multiple times
`generate_stylesheet` method once Gridster is initializated. We use it
at ducksboard to generate a TVmode version of the grid with bigger widgets.
Refactored the way stylesheet tags are removed. When created I push them
to a jQuery collection which is removed when `destroy` method is executed.
Is it possible to add a callback to the resize_widget function, that is
called when the resizing of a widget is finished? This may help to
update the widget content properly.
Right now the number of columns is calculated by dividing the available
space by the necessary space. I want to have an option to limit the
number of calculated columns, without changing the width of the div my
grid lives in.
In order to limit the number of calculated columns max_cols is set to a
number. To have 'unlimited' columns set the value of max_cols to -1 (as
ids done in the default settings). This provides the arbitrary useful
functionality to set the max number of columns to 0. Any sideeffect
caused by this are mitigated by checking that the max_cols is larger
than the min_cols setting.
