createElement?

[JS]

The document object has a method called createElement. Can I use this
method to create a new Drop/down list, like:

var sel = document.create Element('SELECT ');

I have seen it used like this:

opt = document.create Element('OPTION ');

which means that opt now holds an option that can be appended to an already
existing select object.
Are there any restrictions for which arguments createElement can be called
with? I have seen: var oNewNode = document.create Element("LI");b ut what is
"LI"? Where do I need to look to find valid arguments for createElement??

If you are not familiar with HTML there is not much point in attempting
to script an HTML DOM.

The Core DOM applies to many document types. In general you can only
create elements that make sense with the document type you are
scripting. In an HTML DOM you create HTML elements so the HTML
specification effectively lists those elements.
