## Methods summary

`public` | # `__construct( `FormField::$name` $folder )` Create a new field. Create a new field. #### Parameters $folder name The internal field name, passed to forms. #### Overrides `CompositeField::__construct`
`public `FieldSet`` | # `getChildren( )` Accessor method for $this->children Accessor method for $this->children #### Returns ``FieldSet`` FieldSet #### Overrides `CompositeField::getChildren`
`public` | # `FieldHolder( )` Returns a "Field Holder" for this field - used by templates. Forms are constructed from by concatenating a number of these field holders. The default field holder is a label and form field inside a paragraph tag. Returns a "Field Holder" for this field - used by templates. Forms are constructed from by concatenating a number of these field holders. The default field holder is a label and form field inside a paragraph tag. Composite fields can override FieldHolder to create whatever visual effects you like. It's a good idea to put the actual HTML for field holders into templates. The default field holder is the DefaultFieldHolder template. This lets you override the HTML for specific sites, if it's necessary. #### Overrides `FormField::FieldHolder`
`protected` | # `getAssetList( )` Creates table for displaying unused files. Creates table for displaying unused files. #### Returns AssetTableField
