使用ExecCommand插入多级无序列表

Question

I have a javascript WYSIWYG editor I'm creating using "execCommand" and I'm wondering how to go about creating a multi-leveled bullet list using this command.

Currently I have a button which executes this code on the editor to create an unordered list:

WYSIWYG.document.execCommand('InsertUnorderedList',false,'NewUL');

My problem is that if I want to create a sub level of bullets by pressing the button the javascript obviously just closes the UL.

Any ideas as to how I could create a sub-unordered list?

一种简单的方法是在选择要更改的项目时使用indent和outdent命令：

WYSIWYG.document.execCommand('indent', false, null);
