Hiding a Custom Tab and Defaulting to the Items Tab on Page Load in NetSuite

This article explains how to use a Client Script in NetSuite to hide a specific custom tab on record forms and automatically switch to the standard “Items” tab when the record is loaded.

Objective:

To improve user experience or enforce business process rules by:

• Hiding a custom tab with internal ID custom1437.
• Automatically navigating the user to the “Items” tab on page load.

Sample code:

function pageInit(scriptContext) {
        try {
            let currentRecordObj = scriptContext.currentRecord; // Access the current record
            // Fetch DOM elements by their rendered NetSuite IDs
            let tab = document.getElementById('custom1437txt');  // ID of the custom tab
            let itemsTab = document.getElementById('itemstxt');  // ID of the standard Items tab
            // Hide the custom tab if it exists
            if (tab) {
                tab.style.display = 'none';
            }
            // Automatically switch to the Items tab
            if (itemsTab) {
                itemsTab.click();
            }
        } catch (e) {
            log.error("Error in pageInit", e);
        }
    }
