Hide an option from drop down

[Jen11]

Hello,

I have two drop down fields.  Depending on what is selected from the first drop down i would like to hide an option from the 2nd drop down field.  How can I do that?

Hi @Jen11

Hi @Jen11 
For 2nd drop down in which you want to remove, don't add choices manually.
Create an onchange client script on 1st dropdown variable and try this script with your fields and choice names

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        g_form.addOption('choice_2', 'optionA', 'OptionA');
        g_form.addOption('choice_2', 'optionB', 'OptionB');
        g_form.addOption('choice_2', 'optionC', 'OptionC');
        return;
    }

    g_form.addOption('choice_2', 'optionA', 'OptionA');
    g_form.addOption('choice_2', 'optionB', 'OptionB');
    g_form.addOption('choice_2', 'optionC', 'OptionC');

    if (newValue == 'calgary') {
        g_form.removeOption('choice_2', 'optionB');
    } else if (newValue == 'edmonton') {
        g_form.removeOption('choice_2', 'optionA');
    }

}
