Hi @RavikumarY ,

You can achieve this behavior using a Catalog Client Script (onChange) in ServiceNow.....

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading) {
        return;
    }

    // Field names – replace with your actual variable names
    var locFieldName = 'location';
    var countryFieldName = 'country';
    var cityFieldName = 'city';

    // If location changed to "Offshore"
    if (newValue === 'Offshore') {
        // Set country to India
        g_form.setValue(countryFieldName, 'India');

        // Clear city options and add only specific ones
        g_form.clearOptions(cityFieldName);

        // Add cities
        g_form.addOption(cityFieldName, 'Hyderabad', 'Hyderabad');
        g_form.addOption(cityFieldName, 'Bengaluru', 'Bengaluru');
        g_form.addOption(cityFieldName, 'Chennai', 'Chennai');

        // Optionally set a default city (say Hyderabad)
        g_form.setValue(cityFieldName, 'Hyderabad');

    } else {
        // If location is not offshore, maybe reset country & cities

        // Reset country
        g_form.setValue(countryFieldName, '');

        // Clear city options and restore all city choices (if you have static list)
        g_form.clearOptions(cityFieldName);

        // Example of adding back all city options
        // these should include the others that were removed earlier
        g_form.addOption(cityFieldName, 'Hyderabad', 'Hyderabad');
        g_form.addOption(cityFieldName, 'Bengaluru', 'Bengaluru');
        g_form.addOption(cityFieldName, 'Chennai', 'Chennai');
        g_form.addOption(cityFieldName, 'Mumbai', 'Mumbai');
        g_form.addOption(cityFieldName, 'Delhi', 'Delhi');
        // etc.

        // Optionally set city to blank
        g_form.setValue(cityFieldName, '');
    }
}
