Make Dropdown value according to another field

[avinashdube]

Hi , i have requirement to make the dropdown value dependent on a catalog item

When the user selects the option ‘Change Cellular Solution’ under ‘Service Type’ and progress to the next field i.e., ‘Solution Type’, then it should display the below 4 options in its dropdown menu.

1. Private Line Reimbursement.
2. Bring Your Own Device (BYOD).
3. Change carrier.
4. Change ownership (Porting/Mobility).

But for 'New cellular solution' it should display the existing 2 choices only in its dropdown.

i.e.,

1. Private Line Reimbursement.
2. Bring Your Own Device (BYOD).

I tried creating a UI Policy and action but not able to figure out the logic

You can write an OnChange client script on "Service type" field.

Like this:

var serviceType= g_form.getValue('<backend value of Service Type>');

if(serviceType=='<backend Value of Change Cellular Solution>'){
g_form.clearOptions('<backend value of Solution Type>');
g_form.addOption('<backend value of Solution Type>', 'Label 1', 'Value 1', 100);
g_form.addOption('<backend value of Solution Type>', 'Label 2', 'Value 2', 200);
//and so on
}
else if(serviceType=='<backend Value of Change Cellular Solution>'){
g_form.clearOptions('<backend value of Solution Type>');
g_form.addOption('<backend value of Solution Type>', 'Label X', 'Value X', 100);
g_form.addOption('<backend value of Solution Type>', 'Label Y', 'Value Y', 200);
//and so on
}
