I'm not able to format my code in IntelliJ.
I can see the margin line (by default at 120 columns) but it seems that the activation from the menu:
Code -> Reformat Code
is just ignoring this margin.

Enabling "Ensure right margin is not exceeded" doesn't work for me in Intellij IDEA 2018.2. I have found the workaround, we need to change every elements below from "Do not wrap" to "Wrap if long".
After that, we can preview what kind of wrap type will be changed by looking into right panel. If we are satisfied, Click "OK" or "Apply" to apply the changes. Finally we need a mannual format by using CTRL+ ALT+ L in Windows and Command+ Shift+ L in MacOS.
In order to wrap text in the code editor in IntelliJ IDEA 2020.1 community follow these steps:
Ctrl + Shift + "A" OR Help -> Find Action
Enter: "wrap" into the text box
Toggle: View | Active Editor Soft-Wrap "ON"
In the latest IntelliJ, version 2020, we have an option called soft-wrap these files:
Settings > Editor > General > soft-wrap these files.
Check this option and add the type of files you would like to apply the wrapping to.
