Why doesn't catalog.section.list make it into the navigation chain?

Question

1C-Bitrix

Good afternoon everyone
There is a section on the client's site that uses 3 components:
1. catalog.section.list - to display the section with categories is on the index.php page


2. catalog.section - to display the section elements is on the section.php page


3 .catalog.element - for the detailed page of the element is located on the page element.php


4. Infoblock settings


I need the name of the infoblock "Accommodation" to be included on all three pages in the navigation chain, please tell me something

Answer 1

Before catalog.section.list or catalog.section , add a breadcrumb via the $APPLICATION->AddChainItem API. The standard catalog.section and catalog.section.list components do not add IB to breadcrumbs. They add information from sections and elements.
