I learned to add an e-commerce channel through the introduction below (I deleted the link because there is a problem with the display. The specific content should be found at http://www.rainbowportal.net/rainbow/default.aspx's documentation)
The procedure is briefly described.
1. Add a root level tab (as a channel) (assuming you name it the mall)
Note: You need to enter menumsshop In the Interface Options> custom Layout (this is a bad place for Rainbow)
2. Add a product module to the mall page
3. Edit the properties of the product module to select one configuration from the drop-down menu of the following items.
If currency chooses yuan renminbi and the other three, you can choose the option with demo.
4. Confirm and click Modify to generate.
5. add several new pages as sub-pages of the mall (she is the categories of the product). The new page name can be Domain Name Space or camera...
6. After the modification is generated, you can add your product to the subpage you just added at the front-end as an administrator. There are many options and input items, and the bottom category drop-down list contains your child page names.
I hope I have made it clear!
