How to change the map on each item?

Question

1C-Bitrix

I just started to study the backend in depth, and the task is this: When you open a link, a modal window appears and there are 3 tabs in it, and each tab has its own dynamic information, so how to make each item have its own Yandex map in this modal window? (coordinates changed)
CMS: bitirix

And in general, such a question, I studied the front for a long time and want to become a full stack developer, I studied php / database / wordpress at the university, but you yourself understand that they gave only the basics, when they gave me, it’s not easy for me task, and I don’t know at all where to get information on php / backend in general, etc. I just have to remember from experience, some methods, etc.
Does anyone have good sources, books? Thanks guys in advance

Answer 1

I'm a newbie myself, but did something similar a couple of days ago. Create a property for these items in the infoblock in the required format, fill in a couple of items, then google "display infoblock property".
There seems to be something like:

<? echo $arResult['DISPLAY_PROPERTIES']['СИМВОЛЬНЫЙ_КОД_СВОЙСТВА']['DISPLAY_VALUE'];?>

Collected the card without knowing anything.
