Inject a new class in form wrapper - UPDATE ... customization issue

[techbill]

I wanted to style my form inputs etc but I need to inject a class on my form wrapper itself.

The one that have those default classes

class="mauticform-page-wrapper mauticform-page-1".

I am using responsive framework script on my website and I wanted to add grid-x to this class so I could use the classes to size and order the each inputs etc. Like this

class="mauticform-page-wrapper mauticform-page-1 grid-x".

I tried adding class in the Form attributes but that the form itself and I need to add it to the class of the wrapper inside the form.

Doable? via theme?

I know all the Zurb Foundation framework classes or Bootstrap3/4 framework classes but I needed the form framework wrapper class applied to it before I could use those classes on inputs.

Feedback welcomed!

Thanks

I found this document …

https://developer.mautic.org/#form.html.twig

I copied the form.html.php over to my theme folder which I created from blank. Added the desire classes into the form.html.php.

Uploaded theme and selected it in form setting . It doesn’t seem to apply the classes I added to it.

Here my theme structure

Am I missing something?

I got it figured out …

When I uploaded the theme … it extracted all file but the form.html.php … It did not get extracted so I had to upload this one manually directly to the Builder folder and it finally appended those classes for me.

Anyone know why form.html.php goes not get extracted into the themes folder when it is already included in the package? A bug?

The style.html.twig which is also in same folder in the package is extracted successfully.

Here my attempt on first form theme … You can input the column width for each in the field properties.
