hi all,
I am using nodetree as the dynamic source for my selection list. I had
two tips that I would like to share with you.
1. Removing the default -Choose- option:
Hippo has a built-in option to control it, but I don't think it is
documented. Here is how it works:
It's controlled by a param called "choose-item", by default it's
true. To remove the -Choose- option, you have the define your
business-logic.xml like this:
<rule for="/root/myselect">
<selectionsource src="mysource.xml" type="nodetree" dynamic="true"
choose-item="false"/>
</rule>
2. Display childnodes
From the documentation I got the impression that all childnodes will
be displayed like "parent > child", but apparently it doesn't. So I
modified this transformer:
<hippo-cms>/sites/hippo-cms/editing/cf2/cocoon-cform-xmleditor/transform
ers/nodetree2selectionlist.xsl
I extracted the logic that prints a node as a template, and applied
this template recursively to the child nodes. Since I was using
shootbox, where the selection list gets sorted alphabetically every time
an item is removed from the selected box, I prepand the entire parent
path to child nodes to preserve the parent/child order after sort. This
makes the options very long though - I am still trying to set width for
shootbox widget, but so far with no success. Anyone has a lead on that
please help me out! Thanks!
I attached my copy of the nodetree2selectionlist.xsl at the end the
email. Hopefully it's helpful to people using dynamic selection lists
like me.
Regards,
Jun
