Multi-step install wizard on Yii2?

Question

Yii

There is a standard template for a landing page, there is a database of some products. You need to write a multi-step process for installing a landing page, during which a choice will be given which product will be displayed in the landing page.
The selection and configuration of landing blocks is done during installation. For example, there is an iPhone, and, say, Samsung (any) - no matter what technical details they have, like smartphones, it is important that these are two smartphones.
When installing a landing page on a hosting, you need to give a choice of which product will be displayed in the landing page, knowing that the navigation for all products and the number of blocks are the same, only the content that is pulled from the database during installation changes
1. Please advise how to implement such an installer?
2. How to display a list of products during installation, which the user selects for display on the landing page during installation?
3. How to organize the storage of content for products (descriptions, graphic elements of smartphones) for selection during the installation of a landing page on the server?
Thank you.

Answer 1

Well, if we talk about a step-by-step installer, then I made several div blocks. The first one is open, all the others are hidden. Well, "before" back, of course you hide the first one, show the second one, etc.
