Optgroup arrays

[system]

Hello,

I’m trying to create an select box utilizing the optgroup tag. The select box should list all the parent jobs as the label and the child jobs as the options.
I have the parent jobs listing, but the problem is getting the child jobs to group with the correct parent job.

Parent Jobs
$parent_job_list = get_parent_job_list();

Child Jobs
$child_job_list = get_child_job_list($job_id);

[code]

Job: ALL {section name=par loop=$par_job_list} {section name=job loop=$child_job_list} {$child_job_list[job][0]}, {$child_job_list[job][1]} {/section} {/section} [/code]
