How to set dependent values for Selectbox - Service Catalog

[natashamachado]

Hi, guys

There's a need for me to create an catalog item which has 2 variables.

One of them would be a Selectbox with many options.

The second one, would also be a Selectbox (or a Reference field) that depends on the first one's answer. 

Example:

If the user selects "A" for first variable, it should appear the options "2" and "3" at the second variable.

If the user selects "B" for first variable, it should appear the options "4" and "5" at the second variable.

What's the best practice when it comes to this need?

We understood that a catalog client script for this wouldn't be fitting because there's too many dependent values, unless we created an auxiliar table for that.

Kind regards,

Natasha Machado.

Hi,

I did something similar in the past, I've found very useful the procedure described below, feel free to try!

Hope this will fit your need.

this seemed interesting, the example appears to rely on custom tables, can the approach be used on choice variables just added to Select box or other variable types (checkboxes etc) ?

if so, advisement on the code tweaking would be welcomed!

This can also be achieved by using the client script functions like g_form.addOption() and g_form.removeOption() and g_form.clearOptions().

While using these, make sure to add the label as well as index along with Value.

Ex: Use

g_form.addOption('environment', 'DEV', 'DEV', 100);

g_form.addOption('environment', 'TEST', 'TEST', 200);

g_form.addOption('environment', 'PROD, 'PROD', 300);

Instead of

g_form.addOption('environment', 'DEV');

g_form.addOption('environment', 'TEST');

g_form.addOption('environment', 'PROD');
