Redirect to a specific tab in a page after node submit I'm working on Drupal 8.9.6.
I'm trying to redirect users to a particular page after they add a node. I can do that without any problem, by adding the following information in the form's URL:
/node/add/author/edit?destination=/author-list

However, when I try to have a specific tab of the destination page opened, as follows:
/node/add/author/edit?destination=/author-list#tab2

It directly redirects me to /author-list, ignoring the #tab2 part. While if I enter in the browser /author-list#tab2 I get the /author-list page with the #tab2 active without problem.
Does anyone know what could be happening?
Thank you!
Most if not all browsers strip the hash (fragment) and this information is lost so you can't rely on hash being in the URL.
RFC 3986 states:

the fragment identifier is not used in the scheme-specific
processing of a URI; instead, the fragment identifier is separated
from the rest of the URI prior to a dereference, and thus the
identifying information within the fragment itself is dereferenced
solely by the user agent, regardless of the URI scheme. Although
this separate handling is often perceived to be a loss of
information, particularly for accurate redirection of references as
resources move over time, it also serves to prevent information
providers from denying reference authors the right to refer to
information within a resource selectively.

Possible workaround:
Create a hidden input field url_fragment and make sure it passes as a URL parameter (&amp;url_fragment=hashvalue). Have some javascript execute on load of this page and if it finds the url_fragment in the URL make it do a scrollTop and opening of the specific tab.
Here is a question and answer that does the scrollTop if the urlParemeter EXISTS.  You need to modify this script to get the actual value and also click the Tab.
