Hi there,
I was wondering which method to add custom fields in admin area is the best or maybe that depends on something?

Method 1:

function getCMSFields() {
  $fields = parent::getCMSFields();

  $fields->addFieldToTab('Root.Main', new TextField('MyTextField'));
  $fields->addFieldToTab('Root.Main', new TextareaField('MyTextareaField'));  
		
return $fields;

Method 2:

function getCMSFields() {
  $fields = parent::getCMSFields();

  $fields->addFieldToTab('Root.FleetPreview', TextField::create(‘MyTextField’));    
  $fields->addFieldToTab('Root.FleetPreview', TextareaField::create(‘MyTextareaField’));
		
return $fields;

Method 3:

function getCMSFields() {
  $fields = FieldList::create(

    TextField::create(‘MyTextField’),
    TextareaField::create(‘MyTextareaField’)

  );

return $fields;

What are the real differences besides syntax ?

Cheers,
Darek.
