# Horizontal portals addon

## What does it do?

It gives you the option to make horizontal portals

{% hint style="danger" %}
Horizontal portals do not work custom blocks as frame. (custom portal inside and lighter works fine)
{% endhint %}

## How is it configured?

```yaml
Addon:
  HorizontalPortal: '<input>'
```

You can use "false", "true" and "both"

* false: no horizontal portal
* true: the portal is now horizontal
* both: this portal can be built as vertical and as horizontal and they can link with each other
