nn_multiselect: An widget to make more user friendly interfaces
for a multiselect box, using Mootools
Usage:
Link to this file, then add
window.addEvent('domready', function (){
$$('.multiselect').each(function(multiselect){
new MTMultiWidget({'datasrc': multiselect});
});
});
to your page, where '.multiselect' is a selector that picks out a class of
<select MULTIPLE> framework. This element acts as the data source for the
widget. Then create a css file and style the widget however you'd like.
Options: add these to the object you pass to the MTMultiWidget constructor.
Only datasrc is required.
widgetcls:
The css class applied to your final widget.
Default is 'nn_multiselect'
datasrc:
A select multiple dom object
selectedcls:
The css class of the selected list item.
Default is 'selected'
case_sensitive:
Determines if the filter form is case_sensitive or not
Default is False
