USE

All field keywords beginning with html_form_ are passed directly into the form hash. Thus, they are really defined in form.tt which ships with Gantry.

html_form_onchange sets Javascript to execute when a field of type select changes. Usually this is something like:

    html_form_onchange `some_function()`;

It's up to you to make sure the wrapper or template defines the Javascript function.

EXAMPLE

To see an example, build:

    bigtop -c example.bigtop all

Change to the newly created Kids directory and look in the form method in lib/Kids/GEN/Child.pm.
