How do I add an anchor attribute to a route?

Question

I've created a route:

regions.taxonomy_term.edit_form_header:
  path: '/taxonomy/term/{taxonomy_term}/edit'
  defaults:
    _entity_form: 'taxonomy_term.default'
    _title: 'Edit term'
  options:
    _admin_route: TRUE
  requirements:
    _entity_access: 'taxonomy_term.update'
    taxonomy_term: \d+

But now I can't add to path anchor attribute.

For example:

path: '/taxonomy/term/{taxonomy_term}/edit#header'

Answer 1

Thanks everyone!

I have solution my for problem. You just had to add it to this my_module.links.contextual.yml file.

regions.taxonomy_term.edit_form_header:
  title: Edit this block
  group: region_taxonomy_term
  route_name: regions.taxonomy_term.edit_form_header
  weight: 10
  options:
    fragment: 'edit-group-header'

Answer 2

This is not possible because the anchor tag is never sent as part of the HTTP request by any browser, it is only interpreted locally within the browser.

RFC 1808 Section 2.4.1 - "Note that the fragment identifier is not considered part of the URL."
