Form fields
Form fields can be added to sections or table cells with addFormField.
$section->addFormField('textinput')
->setName('name')
->setDefault('Default value');
$section->addFormField('dropdown')
->setName('color')
->setEntries(['Red', 'Blue']);
The supported types are textinput, checkbox, and dropdown. The ODText
writer serializes them as native ODF form controls and preserves their names,
values, and dropdown entries.
