Option Form Element

The <option> element lets you specify allowable choices for a field, which can be represented in a drop down, for example. It's represented by the dw.web.FormOption API class.

Attribute	Description
optionid	The identifier of the option.
value	The option's value.
label	The option label value. This field can be a key.
default	The option's default value.

This element must be a child of <options>, with the following structure:

<options>
	<option>
	<option>
	<option>
</options>

The following example specifies a list of identifying password questions in the profile form:

<field formid="question" label="forms.profile.018" type="string" mandatory="false" binding="passwordQuestion">
	<options>
		<option optionid="MothersMaidenName" value="Mother's Maiden Name" label="forms.profile.019"/>
		<option optionid="MakeOfFirstCar" value="Make of First Car" label="forms.profile.020"/>
		<option optionid="FavouritePetsName" value="Favourite Pet's Name" label="forms.profile.021"/>
		<option optionid="FathersFirstName" value="Father's First Name" label="forms.profile.022"/>
		<option optionid="PlaceOfBirth" value="Place of Birth" label="forms.profile.023"/>
	</options>	
</field>

Object Binding

You can also define option data dynamically by binding methods to an object within the form definition. For example, you could modify the previous profile form to dynamically create a list of password question via a custom business object. In the Business Manager, you would create a custom object and then add the questions as attributes. In Studio, you would modify the form so that it binds a passwordQuestion method to the custom object, as follows.

<field formid="question" label="Password Question" type="string" mandatory="false" binding="passwordQuestion">
	<options optionid-binding="UUID" value-binding="UUID" label-binding="question"/>
	</options>
</field>
