Using Matrix Items to Offer Item Options in Your Site
You can use matrix items in your website to offer various options for products you sell, such as size and color. You can set up matrix items by using the Matrix Item Assistant, or you can set up matrix items individually. For more information, see Matrix Items.
Only the parent matrix item appears on lists in your website. If the subitems are priced differently within the matrix, the item price appears as a range. The subitem is selected and added to the shopping cart using the transaction item options. The item cannot be added to the shopping cart until each option has been selected.
For NetSuite billing purposes, each matrix subitem is counted as one individual website item. For example, if you sell an item matrix in your website that includes 25 subitems, each subitem counts as one for a total of 25 website items.
The website shopping cart shows the matrix subitem with the correct price for the options selected. The Item column displays the subitem name. The Options column shows the option combination the customer selected.
A new matrix item may or may not display on your site based on the preferences set for the display of out of stock items. You may need to create an inventory adjustment (Transactions > Inventory > Adjust Inventory), or set the preference for Out of Stock Behavior on the item record or using Web Store Out of Stock Items on the Shopping tab of the Web Site Setup page (Commerce > Websites > Website List).
