Hello!
Guys, tell me what actions are needed to create an ajax filter. You don't need to code for me, just point me in the right direction :)
1. I have the "Dudes" info block, it has all sorts of properties. For example, "name", "smart", "fool".
2. There is a built-in filter Select a dude - "Dude's name" - "fool" - "smart".
3. Accordingly, I write the Name, put a check on one or another parameter.
4. I need to filter and show
I would be grateful for your help, because I myself will fall into this filter :))

1) We read about Ajax in the principles. (There is a separate topic on the forum about Bitrix and Ajax )
2) We read in Bitrix by $APPLICATION->RestartBuffer() (here is a small topic on the forum )
3) We read by FILTER_NAME of the bitrix:news.list component
4) We make a script that checks on the page that the request came from Ajax - using RestartBuffer resets everything that was before it, connects the component and kills the page execution.
In general and related articles can help. For example , here it is written about ajax loading of news (the technology is the same)
