Code Folding

Show code folding outline

note

This option is not available in the new UI. In the new UI, use the Show code folding arrows option instead.

Select this checkbox if you want the code folding icons to be shown in the gutter. Clear the checkbox to hide the icons.

Show code folding arrows

note

This option is available only in the new UI. In the classic UI, use the Show code folding outline option instead.

Display code folding icons in the editor.

From the list, select the way in which the icons for unfolded areas should be displayed:

• Always: code folding icons are always displayed in the gutter.

• On mouse hover: code folding icons appear only when you hover over the gutter.

Gif

Show bottom arrows: display the bottom folding arrows in the gutter as well. Otherwise, only the top arrows are shown.

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 CtrlAlt0T, select either <editor fold> or region...endregion comments depending on the style you need, and name the created custom region. Now, when you select the Custom folding regions option, IntelliJ IDEA will fold such regions when you open your file in the editor.

  Use the Fold '{0}','{1}' ... placeholders to corresponding context expressions from Java/Kotlin code option to show folded substitutions for property key values. Note that using these settings might potentially slow down the .properties file loading.
