RE: [platform-help-dev] Changed behavior of <topic> elements with out hr

["Pomeroy, Christal" <cpomeroy@xxxxxxxxxxxx>]

On a related note, we have observed that there seems to be only one
selection area for each of the nodes, including those that have children, in
the TOC. This means that whether you pick the expand/collapse icon to the
left of the node label, or whether you pick the label itself, you get the
same behaviour (i.e., the node's underlying hierarchy is revealed/hidden). 

This is just a little unexpected:

** On expansion - Expected behaviour: when the tree is in its 'collapsed'
state, you pick the label on the root node expecting just to see the related
topic. If you are interested in the topic, you pick on the '+' icon to its
left to expand the tree. If the node has no associates href, the topic
currently displayed does not change (as per Kari's note below). 
   Actual behavior: as you pick topics, you get the tree, and  if you're not
interested, you have to pick again to hide the tree.

** On collapse - Expected behaviour: when the tree is in its 'expanded'
state, you pick the label on the root node just to see that root topic. 
   Actual behaviour: you pick the root node in your tree, but the tree
collapses and you have to reselect the root node if you want to see the
nested topics again.

Two questions:
1) Was this behaviour also a conscious decision based on usability feedback?
2) Is it possible to process selection events on a expand/collapse icon
separately from selection events on the corresponding node label? (It looks
like they are separate entities since the cursor shape is different when you
hover over one vs. the other.)

Thanks,
Christal

Subject: [platform-help-dev] Changed behavior of <topic> elements
without hrefs


Somewhat recently (although I'm not sure when) the behavior of "empty"
nodes on the nav tree changed. In the past, when you clicked on a <topic>
element that has a label but no href, the node would expand (if it had
children), and nothing would happen in the content frame; if you had
previously been viewing a topic, it would not go away. Now, when you click
on <topic> with no href, the content frame clears. We have been designing
our navigation trees based on the previous functionality, which was working
well for us.

Was this a conscious design decision, or an accidental change of function?
If it was the previous, what was the reasoning? If the latter, let me know
and I'll open a defect.

Thanks.
