# Turn diagram languages on or off

Every language is available by default except TikZ. Most sites will never use two thirds of them, and a shorter picker is a kinder picker.

Turning a language off removes it from the picker for new diagrams. It does not affect diagrams already drawn in it.

---

## When you would change this

* Standardising on a handful of languages across a site.
* Reducing choice for a large, non-technical user base.
* Turning something on that is off, TikZ being the usual case.

## What you can set

| **Setting**                 | **What it does**                                                |
| --------------------------- | --------------------------------------------------------------- |
| Language toggles            | One switch per language, in the site settings.                  |
| Presets                     | Minimal, Standard and Complete set the whole list in one click. |
| Effect on the picker        | Disabled languages disappear from the editor picker.            |
| Effect on existing diagrams | None. They still render and still open.                         |

⚠️

**Absent is not the same as off.** A site that has never touched these settings gets the defaults, which means everything except TikZ. Once you save the settings, the saved list is what applies.

## A few things that catch people out

* Rendering is never gated by these toggles. An existing diagram in a disabled language keeps working.
* Writing the toggle list writes the full list, so two admins editing at once can overwrite each other.
* If a language is missing from the picker, this is almost always why. See [Troubleshooting](https://help.gocapable.com/diagrams/troubleshooting.html).
