How to create a section with order acceptance pages in 1C Bitrix?

Question

1C-Bitrix

Dear 1C Bitrix gurus!!! I need to create a section in the online store on the 1C Bitrix platform, consisting of several pages for receiving orders. Section - acceptance of orders for seals. The first page - accepting orders for IP seals, the second - legal entities, etc. The condition for the client to place an order without leaving one page. Those. on one page of a subsection (for example, IP printing) there should be steps - 1 selection of a thumbnail (overview of thumbnails with the possibility that the detailed page opens immediately), 2 - selection of the body (the detailed page opens immediately), 3 - a web form with filling in print data and at the end a button to go to the cart. I created such pages by arranging different components on one page - elements of sections, sections and web forms. Without creating an information block. As a result, all links on the site went astray. And detailed pages opened in other windows. I ask you to suggest an algorithm for solving my problem.
