数字字典为key -value对，使用一个通用方法如下
1.

@IocBean
public class SysDicSelectOptionTag extends GeneralVarTagBinding {
    @Inject
    private SysDictService sysDictService;

    @Override
    public void render() {
        String dicCode = Strings.sNull(this.getAttributeValue("code"));
        Sys_dict dict;
        if (Strings.isNotBlank(dicCode)) {
            dict = sysDictService.fetch(Cnd.where("code", "=", dicCode));
        }else{
            return;
        }

        String parentId= dict.getId();

        List<Sys_dict> lst= sysDictService.query(Cnd.where("parentId","=",parentId).asc("location"));

        for (Sys_dict channel : lst) {
            this.binds(channel);
            this.doBodyRender();
        }
    }
}

加入tag
```
<#dic_bycode_list code="workflow" var="o2">
${o2.name!}
</#dic_bycode_list>

别忘了注册在setup.java

for (ViewMaker vm : config.getViewMakers()) {
if (vm instanceof BeetlViewMaker) {
((BeetlViewMaker)vm).groupTemplate.registerTagFactory("dic_bycode_list", ()->ioc.get(SysDicSelectOptionTag.class));
}
}

```
