1.there are two area with title (TitledBorder).
2. the content is a item list can be selected.
@jbm How can I implement this UI? Do you have any good Suggestions?
You could use a combination of a table and a JScrollPane.
But I am not sure what your question is.
Features like a scroll-able panel and panels with Titled borders are not available to a HTML based URCap.
You need to build a JavaSwing based URCap. Instructions to do this can be found on the Getting Started section of this page. After that its a matter of looking up the functionality of different components, like the
JScrollPane and the
TitledBorder for example.
