/**
|
|
* Lets you include a nested group of fields inside a template.
|
|
* This control gives you more flexibility over form layout.
|
|
*
|
|
* Note: the child fields within a field group aren't rendered using FieldHolder(). Instead,
|
|
* SmallFieldHolder() is called, which just prefixes $Field with a <label> tag, if the Title is set.
|
|
*
|
|
* <b>Usage</b>
|
|
*
|
|
* <code>
|
|
* FieldGroup::create(
|
|
* FieldGroup::create(
|
|
* HeaderField::create('FieldGroup 1'),
|
|
* TextField::create('Firstname')
|
|
* ),
|
|
* FieldGroup::create(
|
|
* HeaderField::create('FieldGroup 2'),
|
|
* TextField::create('Surname')
|
|
* )
|
|
* )
|
|
* </code>
|
|
*
|
|
* <b>Adding to existing FieldGroup instances</b>
|
|
*
|
|
* <code>
|
|
* function getCMSFields() {
|
|
* $fields = parent::getCMSFields();
|
|
*
|
|
* $fields->addFieldToTab(
|
|
* 'Root.Main',
|
|
* FieldGroup::create(
|
|
* TimeField::create("StartTime","What's the start time?"),
|
|
* TimeField::create("EndTime","What's the end time?")
|
|
* ),
|
|
* 'Content'
|
|
* );
|
|
*
|
|
* return $fields;
|
|
*
|
|
* }
|
|
* </code>
|
|
*
|
|
* <b>Setting a title to a FieldGroup</b>
|
|
*
|
|
* <code>
|
|
* $fields->addFieldToTab("Root.Main",
|
|
* FieldGroup::create(
|
|
* TimeField::create('StartTime','What's the start time?'),
|
|
* TimeField::create('EndTime', 'What's the end time?')
