title: How to set up a multi-language project in IntelliJ IDEA
body: <p>Is there a way to open/import an IntelliJ IDEA project which contains different language source files? For example I have Java (Maven) + HTML + JavaScript and, unfortunately,  I'm able to import only the Maven project. Is there a way to open/import the entire project as a single whole?</p>
  
  <p>Thanks in advance!</p>
