Plugin Adminimize (add a custom metabox in post type)

Hello,

I’m a french man and excuse me for my english. This plugin is really wonderfull for me !
I have a question. I would add in a custom metabox in the edit form of a post type for the plugin “Google Doc Embedder”.

I do not know what to write in “Name option” textaera (May be Google Doc Embedder) and in “TD classe CSS” textaera.

Can you help me please ?
