if ...else 语法错误
<#macro select id datas value="">
<select id="${id}" name="${id}">
<option>---请选择---</option>
<#list datas as data>
<#if value == data>
<option value="${data}" selected>${data}</option>
</#if>
<#else>
<option value="${data}">${data}</option>
</#list>
</select>
</#macro>

正确做法：
<#macro select id datas value="">
<select id="${id}" name="${id}">
<option>---请选择---</option>
<#list datas as data>
<#if value == data>
<option value="${data}" selected>${data}</option>
<#else>
<option value="${data}">${data}</option>
</#if>
</#list>
</select>
