I would like to create a twig template for the form displayed inside the paragraph widget.
The only way I found is:
function mymodule_field_widget_paragraphs_form_alter(&$element, &$form_state, $context) {
// Check that the subform is opened
if (count($element['subform']) > 2) {
$element['subform']['#theme'][] = 'form__aw_calculator';
}
...
}
After that, I have created a twig template form--aw-calculator.html.twig
like the following
<form{{ attributes }}>
<div class="grid--all three--columns">
<div class="column column--first bg--red-level-3">
{{ element.field_calc_ts }}
{{ element.field_calc_ts_greenlight }}
{{ element.field_calc_budget }}
....
Unfortunately, this is half working... some of the fields are displayed some other are not (the form mode used in the paragraph widget setting should display all of them)
More over, I can't see the markup coming from my twig....
I have the feeling that this is not the right way to handle this... any idea ?
