The Cascade settings include a checkbox labeled "hide cascade". This setting
creates a cascade that's completely functional but not automatically
used on any join forms. Place a hidden cascade on your
join form template by hard-coding the cascade option in a radio button
or a join form submit button.
Hiding a Cascade
In NATS's Billers Admin click the Edit icon of the cascade that
you want to hide.
Manually Adding a Cascade to a Join Form
After a cascade is hidden, it no longer appears on any join forms.
To include it on a join form, use one of the following options.
Figure 1.4 - Join Form - Using a Hidden Cascade
Figure 1.5 - Join Form - Built-in cascade method listing
Figure 1.4 illustrates HTML code that puts the cascade short name in a
HTML option. This contrasts with the standard template content found in
Figure 1.5 - normally, NATS dynamically loops through each cascade
that's available for the given site and creates an HTML radio button
control for each one. If a cascade is hidden, it can never be displayed
on a join form in this way; the only way to display a hidden cascade as
an option is to hard-code it, as seen in figure 1.4. You may also place
the cascade value in a hidden form field, such that the surfer will not
be required to select a payment method.
