Suitescript to add selection option upon clicking the custom button so user can choose two options displayed

AI generated answer (using internal Slack threads):

To add a selection option upon clicking a custom button in SuiteScript, you can use the

addSelectOption

method in a client script. This method allows you to add options to a select field dynamically. Here is a sample code snippet:

javascript
function pageInit(type){
    if(type == 'create'){
        var field = form.addField({
            id: 'custpage_selectfield',
            type: serverWidget.FieldType.SELECT,
            label: 'Select Field'
        });
        field.addSelectOption({
            value: '1',
            text: 'Option 1'
        });
        field.addSelectOption({
            value: '2',
            text: 'Option 2'
        });
    }
}

In this example, a select field is created with the id 'custpage_selectfield'. Two options are then added to this field using the

addSelectOption

method. If you want to control the options of one select field based on the selection of another select field in the same Suitelet, you would need to create a client script and attach it to the Suitelet using the

clientScriptModulePath

property. This script would listen for changes on the first select field and update the options of the second select field accordingly.
