Feature: #19856 - Set special ATagParams for links to access restricted pages
=============================================================================

See :issue:`19856`

Description
===========

A new TypoScript option is introduced which allows additional tag attributes to be set
to links of pages which are access restricted by frontend user group
restriction. Usually these links will not be generated, but it is possible to
link them to another page, for example, a special login page:

..  code-block:: typoscript

    config.typolinkLinkAccessRestrictedPages = 13
    config.typolinkLinkAccessRestrictedPages_addParams = &originalPage=###PAGE_ID###

The resulting link to an access-restricted page (e.g. `22`) looks like this:
:html:`<a href="/login?originalPage=22">My page</a>`

The newly introduced option
:typoscript:`config.typolinkLinkAccessRestrictedPages.ATagParams` allows
custom attributes to be added to the current anchor tag.

..  code-block:: typoscript

    config.typolinkLinkAccessRestrictedPages.ATagParams = class="restricted"

This will result in
:html:`<a href="/login?originalPage=22" class="restricted">My page</a>`.

When generating menus via HMENU, the new :typoscript:`ATagParams` option is
also available for custom settings:

..  code-block:: typoscript

    page.10 = HMENU
    page.10.showAccessRestrictedPages = 13
    page.10.showAccessRestrictedPages.ATagParams = class="access-restricted"


Impact
======

Allowing integrators to set custom :typoscript:`ATagParams` such as class attributes or
arbitrary data attributes to use client-side styling via CSS or JavaScript event
listeners to handle such links differently.
