Using Drupal 9+ and Drupal Weform is there a way to have Google Validate the address the user is typing in is valid? Or like on some sites as you type it gives options/suggetions that are valid addresses and you choose the address.  I have been searching for solutions and haven't found anything that works. Trying to help reduce the user error entries that type their addresses in to the webform incorrectly.

This is the summary / hide summary section. Usually when it's blank, it would show up blank. But now when it's blank, this symbol (<) shows up, see picture below. How do I fix this? This did not happen before and have not updated any code since.

I have created a custom entity with only base fields which puts all the data in a single table which can be accessed by an external application. This works well allowing the external application to view and add new records. However amending a record externally updates the MariaDB table but the change is not reflected in Drupal, unless the cache is cleared. Once this is done, the externally amended record is shown in Drupal.

I am suddenly stricken with an unacceptable default date range value, which I understand is now 1900 to 2000 or so.  The vast number of entries I have made over the years begin in the 1800's and only a few extend past 1900.  I'm not sure when this happened but possible from migrating from version 10 to version 11.  Is there a "universal" setting for this default value?  I've seen mention the need to use hook_form_alter().  I'm not a programmer so I'm not clear on how to do this and if it would be necessary for me to change all the forms I have that have date fields.

My apologies for asking what is probably a very dumb question - but if I want to enable comments for Book pages (Drupal 10/11 Book module), which Comment field type should I add? If I go for re-use, I get the ones below Is it one of these, or do I have to create a new comment field, and if so of what nature?

My thanks in advance - and my apologies for probably being less than smart (blush) :-).

I find it strange that Drupal 11 doesn't have a simple module for fields that manage remote images.
For remote images to be inserted into the body of the content, there is CKEditor 5, but if you need a simple field that is not linked to oEmbed providers or similar constraints, we are stuck with Drupal version 10.
This is strange, given that many sites use CDNs to lighten the load on their servers.

Does anyone know if there is a solution?
