Module:If empty

This module is rated as ready for general use. It has reached a mature state, is considered relatively stable and bug-free, and may be used wherever appropriate. It can be mentioned on help pages and other Wikipedia resources as an option for new users. To minimise server load and avoid disruptive output, improvements should be developed through sandbox testing rather than repeated trial-and-error editing.

This module is currently protected from editing.
See the protection policy and protection log for more details. Please discuss any changes on the talk page; you may submit an edit request to ask an administrator to make an edit if it is uncontroversial or supported by consensus. You may also request that this page be unprotected.

This module can only be edited by administrators because it is transcluded onto one or more cascade-protected pages.

Changes to it can cause immediate changes to the Elite Dangerous Wiki user interface.
To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them.

This module supports Template:If empty. See here for test cases.
