I hope you are talking about this:

  1. You use Intellijidea Ultimate that has thymeleaf support
  2. you want for intellijidea to help you suggest variables that were passed to model, i.e.

Here is your Controller

@Controller 
public void someController {
  @RequestMapping("/")
  public String someMethod() {
    model.addAttribute("message", "message");
    return "index";
  }

And here is your "index.html", where when you type "m" you want to see suggestion window with your variable message, right?:

<p th:text="${message}"> </p>

Now if you put this in your "index.html"

<html xmlns:th="http://www.thymeleaf.org"
      xmlns="http://www.w3.org/1999/html">

Then in your th:text="${message}" you should see red squiggly lines saying that "Cannot resolve "message" variable..."

If that is your problem, then I think for now there is no solutions. Check this issue:

https://youtrack.jetbrains.com/issue/IDEA-132738#u=1437590406765

Although there was time when it worked:

https://blog.jetbrains.com/idea/2014/09/intellij-idea-14-ships-advanced-coding-assistance-for-thymeleaf/

Back then variables were set using "Context". Right now Spring is different, and well you can read about in in issue tracker above.

Hope It was what you've asked.

One last note: although variables added to model in @Controller will not be resolved, all Thymeleaf functions that starts with "#" will be available for you. That is helpful anyway.

And last but not the least, here is duplicate of your question:
