Toolbar option is an array of arrays. The default is
[
["bold", "italic", "underline", "strikeThrough", "superscript", "subscript"],
["fontSize", "color"],
["justifyLeft", "justifyCenter", "justifyRight", "justifyFull", "indent", "outdent"],
["cut", "copy", "delete", "removeFormat", "undo", "redo"],
["paragraph", "blockquote", "removeBlockquote", "horizontalLine", "orderedList", "unorderedList"],
["link", "unlink", "image"]
]
and it can be customized. Each array represents a button group and the value represents the name of the button.
Toolbar is provided with the editor configuration as
{
"toolbar": [
["bold", "italic", "underline", "strikeThrough"],
["justifyLeft", "justifyRight", "justifyFull" "outdent"]
]
}
Providing empty toolbar array will enable all default buttons
