custom field SCOPE in universal module

Good afternoon.
I have an extra field in the article. Different materials have different values ​​for this field, for example: № 1, № 2, № 3.

Q: I want to output module that will show only articles with number 2.

FLEXIcontent version 1.5.6 RC9b (r1601)

hello
at first update your flexicontent is too old
after in universal module you can find an filtering scope by flexicontent filed ...
read description ... and it will be done

please tell me if I upgrade a component I can break something?

Hello

if you upgrade:
-- item data will not be broken

-- the fronted appearance maybe different,

if you have custom template they will continue to work, but maybe affected by new CSS
and built-in templates may look differently
and may need updating if you want to use new features

if you have doubts make a full site backup

Regards
