NicEdit is highly configurable by passing the configuration when you create the NicEditor. Pass your configuration when you call:
new NicEditor({CONFIG HERE})
Add .panelInstance('ID TO TEXTAREA HERE') to add the editor to the textarea.
See the examples below:
new nicEditor().panelInstance('area1');
new nicEditor({fullPanel : true}).panelInstance('area2');
new nicEditor({iconsPath : 'nicEditorIcons.gif'}).panelInstance('area3');
{buttonList : ['fontSize','bold','italic','underline','strikeThrough','subscript','superscript']}
{maxHeight : 100}
