How to list nested sub categories articles?
How I can list the articles of sub categories like I have the main category News and all other sub categories Politics, Security, Sports, etc… belong to News category.
Now I want to list the articles belong to all those sub or nested category of News -> politics, security, sports etc…
<txp:article_custom category="here-news-subcategories" limit="10>...

Re: How to list nested sub categories articles?
I usually do this in two steps:
- Get children categories of parent “news” and save in variable
- Output your article_custom tag with the variable as the category attribute
<txp:variable name="news_cats" trim>
<txp:category_list parent="news" exclude="news" children="1" break=","><txp:category /></txp:category_list>
</txp:variable>
<txp:article_custom category='<txp:variable name="news_cats" />' limit="10" … />Remember to use single quotes around the tag in the attribute.
(You can do this as a tag-in-tag without the variable but it quickly becomes hard to read.)
It wasn’t clear if you also want the parent “news” category too. If you do, just remove the “exclude” attribute. If you want multiple levels of sub-categories, use the attribute children="2" (or however many levels you want). See the docs for category_list for more information

As usual, there are many ways, you should describe your requirements more in details. Probably, depth will do?
<txp:article_custom category="news" depth="1" ... />Offline

Hi Rabah,
Dunno why depth attribute of <txp:article(_custom) /> is undocumented. Maybe it’s a 4.9 thing, maybe an oblivion. The idea is to match the subcategories of certain levels:
category="news" depth="0"(default) matchesnewscategorycategory="news" depth="1"matchesnewschildrencategory="news" depth="1-2"matchesnewschildren and grand-childrencategory="news" depthmatchesnewsand its descendants
and so on. Negative depth might match parents too, I don’t remember.

Yes, it can be handy. If history serves, depth was introduced in 4.8.0, but the docs did not follow. This guy’s fault (kidding :-)
