How to remove label star for Sequel columns that are required/NOT NULL

[janko]

I'm using Forme with Roda and Sequel, and Forme is automatically appending the * to the form label on fields whose columns have a NOT NULL constraint. However, I would prefer not to display it, at least not by default. Is there a way to do that? I know I can set required: false on the input, but so far I didn't find a way to set it as default.

The * is wrapped in an attr tag with title="required", so I'm assuming it's easy to hide in CSS. If not, please let me know, and we can probably add support for disabling it at the plugin level.

Thanks, the following works:

abbr[title="required"] { display: none; }

I've noticed the same thing when I styled my forms with custom CSS according to the given design.
I think it would be better not to hardcode abbr tag and allow users to enable/disable that behaviour.

[jeremyevans]

This would break backwards compatibility, so it would have to be opt-in. However, I'm definitely open to making it opt-in.

@janko @v-kolesnikov What do you think of this approach? This allows turning it off easily. I'm open to other approaches if you have ideas in this area.

I'm going to commit the patch above. @janko I'm still open to a PR for a plugin option if you think it is important.

[jeremyevans]

@janko Just as a heads up, I plan to release 2.4.0 early next month.

[colmexdev]

I have a different situation: I'd like to change the title attribute (e.g. i18n or a custom title). I checked what you say and indeed title is hardcoded. What would be the correct way to set the custom title on the <abbr> tag?

Thanks in advance!

[jeremyevans]

There wasn't previously support for that, but I just added it in 4b012b9

[colmexdev]

Just tried it out and it's working! Thank you very much @jeremyevans
