Hi Peter,
I am afraid that the link you gave me could not solve the problem. The
question I asked is about the help element, not the label attribute for data
element.
To clarify my question, here is the code which does not work, but shows
what I intend to do:
<conditional name="blast">
<param name="type" type="select" label="BLAST type">
<option value="blastn">BLASTN</option>
<option value="blastp">BLASTP</option>
</param>
<when value="blastn">
<help>BLAST DNA against DNA</help>
<param...>
</when>
<when value="blastp">
<help>BLAST protein against protein</help>
<param...>
</when>
</conditional>
I tried to set the help content according to the selected type, which
works like a section header to the following param list.
Obviously this does not work. Then I tried a less-fancy way by providing
static help context by adding <help> under select param like
<param name="type" type="select" label="BLAST type">
<help>BLASTN: BLAST DNA against DNA, BLASTP: BLAST protein
against protein</help>
<option value="blastn">BLASTN</option>
Of course it works but in an ugly formatting text. Is there any document
to format it nicely, e.g. a list?
Best regards!
Jun

You can do this kind of thing with one-line Cheetah syntax within the output
XML tag, but it quickly gets very complicated. e.g.
