<!-- Option type -->
<type>select</type>
<!--
It can be either one of the simple form element types, e.g.:
<type>text</type>
<type>select</type>
<type>multiselect</type>
<type>label</type>
...
or it can define a renderer which will be used to create
this configuration field in the edit form.
Renderer is supposed to be a block reference
in 'block_group/block_path' format, e.g.:
<type>mymodule/some_custom_block</type>
-->
<!-- Source values for drop-downs and multiselects -->
<!--
There are two possible ways to define a set of available values.
The first way is to specify the list of available values right here:
-->
<values>
<one translate="label">
<value>1</value>
<label>One</label>
</one>
<two translate="label">
<value>2</value>
<label>Two</label>
</two>
<three translate="label">
<value>3</value>
<label>Three</label>
</three>
</values>
<!--
The second way is to specify the source model,
which must have toOptionArray() public method available.
The method should return an array of values and labels
in the following format:
array(
array('value' => 'value1', 'label' => 'Label 1'),
array('value' => 'value2', 'label' => 'Label 2'),
array('value' => 'value2', 'label' => 'Label 3'),
);
Source model name is specified in usual
'model_group/model_path' format, e.g.:
-->
<source_model>adminhtml/system_config_source_yesno</source_model>
<!-- Additional helper block to be created on the edit form page, optional -->
<helper_block>
<!-- Helper block reference in regular 'block_group/block_path' format -->
<type>module/block_type</type>
<!-- Arguments for the block constructor, optional -->
<data>
<value1>Value1</value1>
<value2>Value1</value2>
<value3>
<one>One</one>
<two>Two</two>
</value3>
</data>
</helper_block>
<!--
Here is the full example of helper block definition
from catalog module widgets:
<helper_block>
<type>adminhtml/catalog_product_widget_chooser</type>
<data>
<button translate="open">
<open>Select Product...</open>
</button>
</data>
</helper_block>
-->
</first_option>
