Hide a Web Store Presentation Tab

To hide a presentation tab without turning off the "Display in Web Site" checkbox, follow the steps below.

1. Navigate to Lists > Web Site > Tabs.
2. Mouse-over the name of the tab you want to hide.  The bottom part of the page should show a URL where the last portion includes the ID (ex: https://system.na1.netsuite.com/app/site/setup/storetab.nl?id=9). In this example, we will use 9 as the ID.
3. Navigate to Setup > Site Builder > Set Up Web Site.
4. Click Appearance subtab.
5. Take note of the Web Site theme.
6. Navigate to Setup > Site Builder > Themes.
7. If the theme from step 4 is a standard theme, click Customize.  Otherwise, click Edit opposite of the theme. 
8. On the Web Site Theme page, click the Body subtab.
9. Enter the following script on the footer field. Note that the number '9' from the string 'tab9' should be replaced with the ID of the tab you want to hide. (see Step 2)
<SCRIPT>document.getElementById('tab9').style.display = 'none';</SCRIPT>
10. Click Save.  If from a standard theme, change the theme on the Web Site Setup page. (see Step 3)

Note:  This solution will avoid the issue on the Log-in Loop on the Web Store. (For more information, search for the article "Resolve Log-in Loop on the Web Store")
