This is just what I needed.
Thanks Adam.
Another question:
I'm using the DIV tag to put in the editor objects with my own information (last question). I'm using the DIV tag because I want it's behaviour for my objects. I want to be able to move and resize it.
When the user selects Properties, the dialog shows the DIV properties (DIV, General, Style Builder) and another one that I've added.
There is any way to create a personal tag, with the same behaviour of DIV, in order that when properties is selected only my dialog is shown?
Thanks in advance.
