If I need to display a picklist like

Elementary School
Grade one
Grade two
Middle School
Grade seven
High School
Grade ..

two questions ---

1. struts OPTION doesn't come with the index level. so how can I display this using struts tag ?

2. If I need to make only those "Grade" selectable and "Elementray/Middle" scholl titles unselectable, I have to use html OPTGROUP, does struts have similar thing ?

Might want to try the O'Reilly 'Jakarta Struts Pocket Reference', very handy!

Look into <option>, <options>, and <optionsCollection>...These combined with the <logic:equals> or a similar <logic> tag can get you pretty much whatever you want in that list.

Oh. Hi guys! Look at this tiny ad:
