how could put a drop-downlist with multiply option on a request page as below?

I create an option variable , an put it on the request page, But I can not get it like that.

can you show us how is it showing?

Hi Gary,
The issue is that you have put them into the Request Page, which means you get the result you show.
If you want to have the option field showed the way you show above, then you need to add it to the ReqFilterFields property of the dataitem holding your field. Then it will show just above the "add filter" option.

Hi Erik, Thanks for your answer, So I can not show it based on a variable right? just can show a field from a dateitem？

Yes, without any coding, then only dataitem fields. And even then, only a similar view.
