By default the fieldset is opened or expanded at start. Click on its legend to close or collapse it.

The code is simply like below

$('#fieldset1').coolfieldset();

If we want the fieldset to be closed or collapsed at start,just add {collapsed:true} as the argument.

$('#fieldset2').coolfieldset({collapsed:true});

You can also define the animation speed for the fieldset while collapsing or expanding by using speed option. Acceptable values are "fast","medium","slow",or a number in millisecond.

$('#fieldset3').coolfieldset({speed:"fast"});

If you don't want to use animation effect,please use animation option and fill its value with false.

$('#fieldset4').coolfieldset({animation:false});

• All content inside fieldset (except the legend tag) should be placed inside the div tag.
• Edit the jquery.coolfieldset.css to change the fieldset style.
