Category Pages
When you create categories with SMT, a category page is created. This page lists the products and subcategories that are assigned to the category. Similar to landing and enhanced pages, a category page lets you set the page attributes, including name, heading, path, title, meta description, addition to <head>, and meta keywords. These settings are displayed in the Category Settings in the side panel. The following screenshot shows each of the three category settings subtabs.

1 – Visibility
Here you can set the visibility options.
Always visible.
Visible on a certain date and time and expires at a certain date and time.
Visible on a certain date and time and does not expire.
2 – Name
This field lets you specify the name for the category. The name identifies the category in NetSuite and can also be used in category navigation.
3 – Heading
The heading is displayed at the top of the category page if the page template file supports it.
4 – URL Fragment
The URL Fragment specifies the section of the URL that is used to go to the category page. The full category page URL is a concatenation of the domain, any parent URL fragments, and the URL fragment you specify here.
5 – Title
The Title field specifies the value to set for the <title></title> element for the page.
6 – Meta Description
The description you enter here is an important Commerce web store consideration. It is normally the description that is included on search results pages. The description is set as the value for the content attribute for the meta description element for this category page.
7– Meta Keywords
This field specifies the value to populate the content attribute of the meta keywords element on the category page.
8 – Add to <head>
The Add to <head> field lets you specify code such as HTML, CSS, or javascript to include between the <head></head> tags on this category page.
