how to create a dynamic mulitple select field based on value of another field

AI generated answer (using internal Slack threads):

To create a dynamic multiple select field based on the value of another field in NetSuite, you can use dependent dropdowns with custom records. Here's a general approach: 1. Create a custom record for your 'Output' field. This custom record should have a field for 'Method', which will store the corresponding 'Method' value for each 'Output' value. 2. Create a custom field for your 'Output' field on the record where you want this functionality. In the 'Source List' field, select the custom record you created in step 1. 3. In the 'Filter Using' field, select the 'Method' field on your custom record. This will filter the 'Output' options based on the 'Method' value selected. Here's a code snippet for creating a select field with a source:

javascript
form.addField({
 id: 'custpage_customer_list', 
 label: 'Customer List', 
 type: serverWidget.FieldType.SELECT, 
 source: 'customer'
})

In this example, the select field is sourced from the 'customer' record type, meaning the options in the select field will be all the customers in the system. Please note that this approach does not require scripting or workflows. However, if you need more complex behavior, you may need to use SuiteScript or SuiteFlow. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
