In version 3 we had a "scope" area where we could choose product visibility... in particular we could hide products from the member.php page. In v4, that option has been removed from what I can tell. So how do I keep certain products from showing on the add/renew page within the members area? Thanks!
That is mainly controlled by the signup form. You can use the Forms Editor to control what items are listed. Note that you can build multiple forms each with a unique URL. Also on the products page in the "Product Availability" section, you can establish conditions that controls when a product is eligible for sale.
In 4.x this option has been replaced with 'blocks' in the signup forms area (configuration/forms), you configure the product block (on the left side of the editing area) to display only certain products. Then in the main form area you can set which of these forms should be shown to logged in members and non-logged in members. David
