nav tag ignores select

[dannyuk1982]

Bug description

selecting fields for the nav tag appears to be ignored and all fields are selected regardless

How to reproduce

{{ nav:main select="title" }}
{{ url }}
{{ /nav:main }}

This still outputs the urls for each entry in the main nav, it shouldn't as they haven't been selected

The select parameter was accidentally removed in Statamic 5.

We have an draft pull request to add it back, but we haven't got around to finishing it off yet, see #10226.

Probably worth removing from the docs until it's back?

A comment on that PR, it's not just useful for speed. Here is a use case:

The hero and top nav area can be green or orange, each page can differ. This is stored for each entry as a variable, i.e. nav_bg. When the view for that entry loads that sets the nav's bg, great.

That entry is also part of the nav, because the nav is part of that nav area, for just that iteration of the loop that nav_bg variable then is different to the current entry's value. This now messes up the colours for the hover state and dropdown colours etc.

Just being able to select only the title/url would fix this.

tl;dr if you could add it back that would be great as it's not just for performance in some cases!

Another common use case for the select parameter is limiting the Json data passed to a VueJS navigation component.

Modifying nav data to Json is also much slower because of the missing select functionality.
