AjasHadi is correct, that if you set a size>=2 the required validation works and does not need any other tricks.
However, this does not solve the issue for those who want size=1, which is common.
In that case, the Note in the required attribute description saying you can use value=" " is correct for Flash format forms only.
This technique does not work for HTML or XML forms, as ipaul noted.
I tried the technique mentioned by apaleja does not seem to work for me, but I may be missing something (and I did change formName and selectName the cfform and cfselect name values.

Ok, I have tested this with many different scenarios and here are the results.

1. The validation works only if you have size attribute of cfselect set to a value greater than 1.

Here is my code that works

2. Here are some observations

a. I didnt require selected="" attribute inside cfselect

b. I didnt require i.e. with a space or without space(either way, I tried and it didnt work)

So try this and I am sure you wont be dissapointed. It took me a while to figure it out and I tried different options before I succeeded.

It is possible use required = 'yes' in a cfselect statement with a little javascripting code to accompany it.

By default, a cfselect and select input type will have whatever is displayed selected. However, using the code below you can 'unselect' the default selection and then the required='yes' cf validation will kick in...

Cheers!

The required tag value=" " as shown below only appears to function correctly with FLASH, but does not work with HTML.

Referring to this:
You can work around this issue: format forms by having an initial option tag with value=" " (note the space character between the quotation marks)."

Documentation should state that the size has to be greater than 1 for the multi select to work in flash. It would be a nice feature to allow multiple selects in a drop down list.

the attribute editable="yes" is missing from the documentation. This will allow a select box that also accepts user input.

FYI, Mike Kaminsky posted an interesting comment on resolving cfselect problems on the following page:

To pass items between cfselect , cftree, cfgrid you have to use a bit of Actionscript. Here is what I did: I have large a tree (three nodes depth), the user selects the node, next using Actionscript I pass this selection to another select by putting some Actionscript code in the onChange event handler

onChange="_root.select_name.addItem(tree_name.selectedNode.getProperty('data').display,tree_name.selectedNode.getProperty('data').value);"

As cfselect becomes listBox component of Flash, we can manipulate it using various predefined methods like addittem(dispy, value)

I hope this helps!
