In a suitelet, how can I make a select field in a sublist mandatory

AI generated answer (using internal Slack threads):

In a Suitelet, you can make a select field in a sublist mandatory by using the

isMandatory

property of the field. This can be done when you create the sublist field (column). Here is a simple example:

javascript
var sublist = form.addSublist({
    id: 'customsublist',
    type: serverWidget.SublistType.LIST,
    label: 'Custom Sublist'
});

var selectField = sublist.addField({
    id: 'customselect',
    type: serverWidget.FieldType.SELECT,
    label: 'Custom Select'
});

selectField.isMandatory = true;

In this example,

customselect

is the ID of the select field in the sublist

customsublist

. The

isMandatory

property is set to

true

, which makes this field mandatory. However, please note that this will make the entire column mandatory. There is no way in NetSuite to set columns mandatory by line. If you want to enforce the mandatory condition on a line-by-line basis, you might need to use a client script with the

validateLine

function to check if the field is filled in before allowing the line to be added. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
