intellij thymeleaf Namespace th is not bound

I am using IntelliJ IDEA and I have with thymeleaf namespaces. I have created employee form which I am including into others templates so I did not specified namespaces but its works fine when I run my application. Is there any way to change this behaviour. I like auto-complete function :-)

  1. Also, if you are using Spring you should use the following:

    <!DOCTYPE html SYSTEM "">
    <html xmlns="" xmlns:th="">

    The difference is in the DOCTYPE. See Intellij Idea: Thymeleaf namespace unkown

  3. To enable auto completion and IDE support for Thymeleaf, make sure you have enabled the Thymeleaf plugin.

    File -> Other Settings -> Config Plugins -> tick Thymeleaf

    Also add the namespace in the root tag

    <html .... xmlns:th="">

  5. There's no harm defining your fragments in a well formed document (including a html, head, body etc). In fact this is how the Thymeleaf Documentation does it.

    This way you can specify the thymeleaf namespace so you get autocomplete, and you can also view your fragments by themselves in the browser, which is useful for prototyping.
