{% embed url="<https://vimeo.com/759930797>" %}

To add a language selector as buttons or links, you must to select the **"disabled"** option in the language selector in the Polyflow app, then, you must create each button or link and add the following custom attribute to it: "**polyflow-link**" = "**\[LANG ISO CODE]"**

{% hint style="info" %}
ISO is a standardized nomenclature used to classify languages, each language is assigned a two or three-letter lowercase abbreviation.

Check out here for a list of ISO codes as you will need to use them to create your language versions: <https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes>
{% endhint %}

For example, if you want to link the English version you must add the following custom attribute to the link element: **"polyflow-link" = "en"**\
Also, if you want to hide that button in the corresponding language, you will have to add a custom Polyflow attribute, **"polyflow-only" = \[ISO CODE]**, to show the button only in the correct language version.

Find [here](/language-custom-content/how-to-show-different-contents-depending-on-the-language-version.md) more information about our attributes, to show or hide content depending on language version.
