Spring JSTL/EL form:select options from comma delimited string

I'm using Spring 3.0.5.

I've got a comma delimited string "A, B, C, D". Is it possible to build the list of options for a form:select input from this string?

I'm looking for something like:

<form:select path="foo.value" cssClass="formInput">
   <form:options items="${myCommaString}"/>
</form:select>

or do I need to do a for each loop?

BalusC is right - <form:options> accepts a collection, map or array of objects. So use fn:split(..) But in your case I'm not sure it will work. A select option needs two strings - a value (sent to the server on submission) and a display value (shown to users). Perhaps it will assume the same for both, so try it. If it doesn't work, you'll need the itemValue and itemLabel parameters.

You can use JSTL fn:split() to split a string on a delimiter into an array of substrings.

<form:options items="${fn:split(myCommaString, ', ')}" />
