Fold by default

Select the code fragments which should be folded by default, that is, when a file is first opened in the editor.

  • File header

  • Imports

  • Documentation comments

  • Method bodies

  • Custom folding regions- blocks of code within matched pairs of curly braces {}, learn more from Expand or collapse code elements.

    For example, select a block of code for which you want to create a folding region, press Ctrl+Alt+T, select either <editor fold> or region...endregion comments depending on the style you need, and name the created custorm region. Now, when you select the Custom folding regions option, IntelliJ IDEA will fold such regions when you open your file in the editor.
