Try the select multiple component in tassel?
Otherwise, the contrib:palette works well, too.
Using it is really about the same as using PropertySelection.
The only difference is that you're passing a (modifiable) list instead
of a single object in.
Here's an example...
<select jwcid="@contrib:Palette" model="ognl:coursesModel"
selected="ognl:selectedCourses"
availableTitleBlock="ognl:components.unenrolled"
selectedTitleBlock="ognl:components.enrolled"/>
<span jwcid="[EMAIL PROTECTED]">
Unenrolled
</span>
<span jwcid="[EMAIL PROTECTED]">
Enrolled
</span>
