Yes, adding a "<when else>" option would be nice. However, what I really would like to have is a way to tell in one select box which other select box(es) should be refreshed when its value is changed by the user. For example: <param name="cmb_col_type" type="select" label="Select column type" param_to_refresh_on_change="cmb_polarity" display="radio" dynamic_options='get_column_type(library_file)' help="" /> <param name="cmb_polarity" type="select" label="Select polarity" display="radio" dynamic_options='filter_column(library_file,cmb_col_type)' help="" /> So when cmb_col_type is changed, the dynamic_options of cmb_polarity are generated again by a new call to the function configured. I can create a Trello card, but I’m just wondering whether this is not already being planned by the team, especially with the Javascript/AJAX rework that is now planned/going on(?) for some time on the user interface?

So I need to refresh on change....I see that if I have a conditional

This is deliberate, although there has been talk of updating the conditional code to do the dependent parameters dynamically rather than server-side with a page refresh. From your outline description, I think you should be using the Galaxy <conditional> tag.
However, it seems that when I have a <conditional> I must have a
<when> entry for every item in my select box. There is no “when else”
option?
I think you are right - I've asked in the past about this, e.g. this discussion which appears not to have been fully on the mailing list though: http://dev.list.galaxyproject.org/Multiple-values-in-lt-when-gt-tags-for-lt-... This probably deserves to be tracked with a Trello Card... Peter
