default value on dynamically added form fields

Forms\Components\Group::make(
  function (Get $get) {
      $collection = $get('component.collection') ?? [];

      return collect($collection)
          ->filter(function ($componentClass) {
              // Ensure the component class is valid
              return class_exists($componentClass);
          })
          ->map(function ($componentClass, $key) {
              // Dynamically resolve the component class and return its schema
              return Forms\Components\Section::make($componentClass::$title)
                  ->collapsible()
                  ->schema($componentClass::getSchema($key)); // Show only if it's the current component
          })
          ->toArray();  // Ensure it's an array of components
          }
    )->live()
Forms\Components\Group::make(
  function (Get $get) {
      $collection = $get('component.collection') ?? [];

      return collect($collection)
          ->filter(function ($componentClass) {
              // Ensure the component class is valid
              return class_exists($componentClass);
          })
          ->map(function ($componentClass, $key) {
              // Dynamically resolve the component class and return its schema
              return Forms\Components\Section::make($componentClass::$title)
                  ->collapsible()
                  ->schema($componentClass::getSchema($key)); // Show only if it's the current component
          })
          ->toArray();  // Ensure it's an array of components
          }
    )->live()
And one of component classes have: 
public static function getSchema (string $key): array
{
    return [
        Forms\Components\TextInput::make($key . '.title')
            ->default('Some default text')
            ->required()
    ];
}
public static function getSchema (string $key): array
{
    return [
        Forms\Components\TextInput::make($key . '.title')
            ->default('Some default text')
            ->required()
    ];
}
Some default text is not appearing.. Anyone know why? Thanks

You can't set a default field on dynamics since defaults are populated once the dom has loaded and not again. You would need to use $set() to set defaults post load. maybe with a $get to check it is empty.

Well I predefined hidden fields for default values and then populated dynamic element like this: 
$this->form($formFields)
  ->icon('heroicon-s-paint-brush')
  ->action(function (Set $set, $data) use ($prefix, $formFields) {
      foreach ($formFields as $field => $value) {
          $set($prefix . '.animation', $data[$field]);
      }
  })->mountUsing(function (Form $form, Forms\Get $get) use ($prefix, $formFields) {
      $existingData = [];
      
      foreach ($formFields as $field => $value) {
          $existingData[$field] = $get($prefix . '.' . $field) ?? '';
      }
  
      $form->fill($existingData);
  });
$this->form($formFields)
  ->icon('heroicon-s-paint-brush')
  ->action(function (Set $set, $data) use ($prefix, $formFields) {
      foreach ($formFields as $field => $value) {
          $set($prefix . '.animation', $data[$field]);
      }
  })->mountUsing(function (Form $form, Forms\Get $get) use ($prefix, $formFields) {
      $existingData = [];
      
      foreach ($formFields as $field => $value) {
          $existingData[$field] = $get($prefix . '.' . $field) ?? '';
      }
  
      $form->fill($existingData);
  });
So basically populate dynamic form with mountUsing. Now I guess i needed to hnave predefined keys in form, so thats why i haave hidden fields, but if u can find other way you can remove it.

Did you find this page helpful?
