How to display the number of pages according to the template or are there other options?

Question

MODX

Closer to the point, there is a menu with a total number of documents.
And the code for it:

Accordingly, when I add the parameter: &templates=`7` . I only display documents according to the pattern "7", and not the number.

Why does it do this? How to output correctly (in my case)?

If you need to display children and their number, then add parents and countChildren
