You could do this a couple of ways (thinking out loud here): 1) Do some preprocessing and build a list of all the objects, but I guess that would only work if your SubCategory class had the same properties for name and ID.
2) Do some preprocessing and add ID/name pairs to a SequenceHashMap (org.apache.commons.collections.SequencedHashMap) and use that as your collection. 3) Don't use <html:options/> but instead use nested <logic:iterate/> tags (for each category, loop over the subcategories in the collection) and use <html:option/> tags with name/value pairs. This is probably the best since it is the clearest as to what you are doing, plus you can create the empty spaces more easily. -- Michael D.
