Update section heading programmatically

Hello, Is it possible to update a section heading programmatically? Or display a form field in it? I would like to display a "total cost" calculated with other fields of the form, in the heading of a section. The issue is that I put a value in the heading like so:

Forms\Components\Section::make()
    ->heading(fn(Get $get): string => (string) $get('total_cost'))

Forms\Components\Section::make()
    ->heading(fn(Get $get): string => (string) $get('total_cost'))

But my "total_cost" field is not defined on a creation form, because it's calculated after some fields are updated. How can I force the update of the heading? IS there a "boot" method on form builder?

Solution:

I finally did what I wanted by calling my "calculateTotalCost" in the heading() closure 👍

->heading(function (Get $get, string $operation) {
    if ($operation === 'edit') {
        return $get('total_cost');
    }
    
    return 'Default Section heading';
})

->heading(function (Get $get, string $operation) {
    if ($operation === 'edit') {
        return $get('total_cost');
    }
    
    return 'Default Section heading';
})

I wish the 'Default Section heading' was $get('total_cost'), even at the creation. By default, the total_cost is calculated by doing some additions of other fields or settings

I mean you probably just need to add live on the section 🤔

Section::make()
    ->live() // <--
    ->heading(fn(Get $get): string => (string) $get('total_cost'))

Section::make()
    ->live() // <--
    ->heading(fn(Get $get): string => (string) $get('total_cost'))

Should do it?

I tested but unfortunately it doesn't work

Mhh i suppose you need to share more code then, because I just tested it, and it does work:

Section::make()
  ->live()
  ->heading(fn (Get $get) => $get('name') ?: 'default heading...')

Section::make()
  ->live()
  ->heading(fn (Get $get) => $get('name') ?: 'default heading...')

🤔

Yes, I will share more code, I'm simplifiying it right now

If I intervert the group and the section, it works as I want... I do not really understand
