hello frd, I'm trying to create a new Tab in Product but I don't find the wat, could u show me how I can do it? thank u!!!

Read the tutorials for extending a basic site

http://doc.silverstripe.com/doku.php?id=tutorial:2-extending-a-basic-site

You add something like this to your class, directly taken from the tutorial:

function getCMSFields() {
$fields = parent::getCMSFields();

$fields->addFieldToTab('Root.Content.Main', new CalendarDateField('Date'), 'Content');
$fields->addFieldToTab('Root.Content.Main', new TextField('Author'), 'Content');

return $fields;
}

hello Lee for u quick answer but it is ok when I want to add field to a tab already existent, but I want to create new tab!!! if u know how I can do it I will be grateful thank u

The line in the above code Root.Content.Main refers to your site structure.

Root is the start/top level, Content refers to the content tab, and main is the main tab. Just change the name to a new tab and it will make it for you.

hello Lee, thank u!!!! it works!!!! now I have another task and I don't know how to start:
I'm using SilverStrip CMS and I want to move the ecommerce module in the top menu and to remove it of site content (the products)!!!! I'm newbie and need a guide how to do it, thank for ur help
