is there a way to add a button to a subtab

AI generated answer (using internal Slack threads):

Yes, it is possible to add a button to a subtab in NetSuite. However, it's important to note that this will add a button to the sublist within the subtab, not the tab itself. You can do this by using the

addButton

method from within a user event script's

beforeLoad

entry point. Here is a sample code snippet:

javascript
function beforeLoad(context) {
    var f = context.form;
    var itemlist = f.getSublist("item");
    itemlist.addButton({id:'custpage_itembutton', label: 'My Item Button'});
    return true;
}

In this example,

context.form

is the form on which the sublist resides,

getSublist("item")

is used to get the sublist named "item", and

addButton

is used to add a button to that sublist. The

id

and

label

properties are used to set the ID and label of the button, respectively. Please note that this will add the button to the sublist, not the tab itself. If you want to add a button to the tab itself, you might need to use DOM manipulation, but this is not officially supported by NetSuite. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
