For making some part collapsible (if I understand your question), you need to use this code:

<div class="block collapse" id="unique id name">
	<h2 class="blockhead">Name of the block, can be phrase, can be hardcoded

<a class="collapse" id="collapse_unique name" href="{vb:raw relpath}#top"><img src="{vb:stylevar imgdir_button}/collapse{vb:raw vbcollapse.collapseimg_cel_dummy_img}_40b.png" alt="{vb:rawphrase collapse_this_category}" /></a>

</h2>
	<div class="blockbody settings_form_border" id="unique name">

-------------here goes code that you want inside collapsible block, whatever it is --------------

	</div>
</div>

In upper example I used CODE BBtag so I can use color BBcode, so you can see in red what are variables you can (and have to) change to suit your needs. The two unique names in green must be the same that collapsing work.

For this particular example you can use this code:

<div class="block collapse" id="usernotes_in_userprofile">
	<h2 class="blockhead"><img src="{vb:stylevar imgdir_siteicons}/note.png" alt="{vb:rawphrase user_notes}" class="inlineimg" /> {vb:rawphrase user_notes} ({vb:raw prepared.usernotecount})

<a class="collapse" id="collapse_usernotesprofile" href="{vb:raw relpath}#top"><img src="{vb:stylevar imgdir_button}/collapse{vb:raw vbcollapse.collapseimg_cel_dummy_img}_40b.png" alt="{vb:rawphrase collapse_this_category}" /></a>

</h2>
	<div class="blockbody settings_form_border" id="usernotesprofile">

<vb:if condition="is_member_of($bbuserinfo,5,6,7)"><div><IFRAME SRC="usernote.php?{vb:raw session.sessionurl}u={vb:raw prepared.userid}" WIDTH="100%" HEIGHT="300"></IFRAME></div></vb:if>
	</div>
</div>

In above example you have for title of collapsible block first image (you can easily remove it), phrase for user_notes and total number of usernotes for that user.

Info about collapse status of the block is kept in cookies, so if you change browser, this info isn't remembered.

I'll also add this info in first post, and I also change location where you need to add this code to have user notes bellow navbar.
