File nesting dialog

This dialog opens when you click File Nesting on the context menu of the title bar in the Project tool window.

Use this dialog to configure presentation of files with the same names but different suffixes.

Such bunches of files may appear in framework-specific projects, for example, if you use Angular:

Also consider compilation of TypeScript into JavaScript with source maps generated:

IntelliJ IDEA can present such file bunches as plain structures or show parent files as folders (nests) with their child files inside. To configure file nesting, set correspondence between the suffixes of parent files and the suffixes of the child files.

IntelliJ IDEA provides a set of predefined rules. You can edit these rules as well as define your own custom ones.

Item	Shortcut	Description
Show files with the same names as nested		When the checkbox is selected, IntelliJ IDEA recognizes child files based on the patterns from the list and shows them grouped under the corresponding parents. Compare the presentation of the above TypeScript example with file nesting enabled: When the checkbox is cleared, IntelliJ IDEA shows parents and children at the same level.
	Alt+Insert	Click this button to add a new row and specify the "parent" file suffix and the matching "child" file suffix.
	Alt+Delete	Click this button to remove the selected rule from the list.
Reset to Default		Click this button to discard all your custom patterns and reload the default rules.
