Hide new (HA 2025.4) title breadcrumb

[Mariusthvdb]

we have a new cluttering kid on the block to hide, a breadcrumb was added to all more-info cards and sub cards.

It serves no real purpose other than for users who didnt rename their entities and have 20 Temperature sensors..

Personally Id set display: none to that.

@elchininet could you maybe see if that is feasible?

[elchininet]

I'll take a look at it later.
Is this change in the beta?

[Mariusthvdb]

yes
see https://rc.home-assistant.io/blog/2025/03/26/release-20254/#other-noteworthy-changes

apparently there's more to come, and it will be sparkled... personally, I find all that info not placed correctly, and cluttering the main point of the more-info.
opinions vary however, so we should take matters into our own hands

[Mariusthvdb]

seems this must be doable with a card-mod theme setting on

  card-mod-more-info-yaml: |

too, but I wasnt successful yet (other than in Inspector directly)
if you could help me out there, a test could be done easily to see if the change would hold everywhere.

You can check the code examples in kiosk-mode for the more-info dialogs. It can give you an idea.

thx, but meanwhile I found the correct path ;-)

  card-mod-more-info-yaml: |
    ha-dialog-header: |
      .breadcrumb {
        display: none;
      }
    $: |
      .mdc-dialog {
        backdrop-filter: blur(17px) !important;
        -webkit-backdrop-filter: blur(17px) !important;
      }

Might be interesting for your Kiosk-mode too btw ;-)

[Mariusthvdb]

and of course, made that conditional, for let's say dev mode:

  card-mod-more-info-yaml: |
    ha-dialog-header: |
      .breadcrumb {
        {% if is_state('input_boolean.hide_more_info_breadcrumb','on') %}
        display: none
        {% endif %};
      }

[Mariusthvdb]

argh... they broke it again during the beta...https://github.com/home-assistant/frontend/pull/24830/files

need to check why my card-mod is not working anymore. as the .title is still in place as far as I see it

[elchininet]

Yes, that is normal. But it is getting closer to the end of the month so what is changed now should be the definitive. I am trying to figure it out what changed that is breaking some custom-sidebar tests.

[Mariusthvdb]

needs !important now..

  card-mod-more-info-yaml: |
    ha-dialog-header: |
      .breadcrumb {
        {% if is_state('input_boolean.hide_more_info_breadcrumb','on') %}
        display: none !important
        {% endif %};
      }

and working again

[Mariusthvdb]

running this in 2025.5.1 still seems reliable
