I started to convert this select from Struts1 to Struts2.
STRUTS1
<html:select styleId="ss" property="type" styleClass="select2" onchange="checkStatus();">
<html:options collection="listOfType" property="value" labelProperty="key" />
</html:select>
STRUTS2
<s:select id="ss" name="type" cssClass="select2" onchange="checkStatus();">
...
</s:select>
But I don't know how to convert the options tag.
You can use list
attribute
<s:select id="ss" name="type" cssClass="select2" onchange="checkStatus();"
list="listOfType" listKey="value" listValue="key"/>
You can read more about <s:select> tag
on Struts docs site.
