This code, which follows the check for drop-down box field, defines how to display the content of

the drop-down box field, if present. Displaying the content of the drop down box requires

denoting which of the available options is selected. If no option is selected, displays the default

value as the selected option:

<%-- ========== --%>

<%-- select box --%>

<%-- ========== --%>

<logic:equal name="customField" property="type"

value="<%=Integer.toString(CustomFieldConst.TYPE_DROP_DOWN)%>">

<%-- iterate over the options --%>

<logic:iterate id="optionValue" name="customField"

property="optionValues"

type="java.lang.String">

//-- if the entry has a value, make it selected. --//

if ( null != customField.getVal() ) {

if ( optionValue.equals(customField.getVal()) ) {

<option value="<%=optionValue%>"

selected><%=optionValue%></option>

} else {

}

//-- the entry has no default, make the default option selected.

--//

} else {

if ( optionValue.equals(customField.getDefaultValue()) ) {

<option value="<%=optionValue%>"

selected><%=optionValue%></option>

} else {
