How can I open .zul file in Intellij?

Question

I have downloaded the ZK plugin, but when I create a .zul file, it is just recognized as an unknown file for intellij. I tried resetting cache and rebooting, didn't make a difference..

Is there a way to connect the plugin to the extension? Am I missing something here?

Answer 1

I had quite the opposite experience, I created a .zul file and IntelliJ automatically suggested something like: "There's a plugin available that handles .zul files, would you like to install download and it?" -> confirmed and restarted ... Then .zul files are registered as XML files under Settings/File Types and code completion is working.

Not sure how this is failing for you, can you provide your version details including the plugins installed?
