As for why, my code is based on this: http://stackoverflow.com/questions/3798262/how-to-collapse-a-paragraph although i've been improving it. The idea is add or remove a paragraph block below the expander block based on the state of the expander. That + code to handle the copy to clipboard to convert the uielements to text (in this case, getting the header string of the expander) and the result is an interactive flowdocument with collapsing regions and copy support.
