[daisy] Document node shows expanded

[ddas at lexmark.com]

I have created a 'Document Node' under the root folder using the Navigation
editor and have added some group nodes under it. However, when I click on
any other 'Document Node' under the root folder, the previous one shows
expanded even if it was not (in the first place).  Is this normal
functionality or do I have control over expansion/collapse of
document/group nodes?
