# Slot ViewHelper `<f:slot>`

`f:slot` allows a template that is called as a component to access and render
the child content of the calling component tag. This makes nesting of components
possible.

Most importantly, the `f:slot` ViewHelper makes sure that the right level of
HTML escaping happens automatically, in line with the escaping in other parts of
Fluid: If HTML is used directly, it is not escaped. However, if a variable is
used within the child content that contains a HTML string, that HTML is escaped
because it might be from an unknown source.

In combination with the [\<f:fragment> ViewHelper](https://docs.typo3.org/permalink/t3viewhelper:typo3fluid-fluid-fragment@13.4),
multiple slots can be used in one component.

If a slot is defined, this ViewHelper will always attempt to return a string,
regardless of the original type of the content. If a slot is not defined, the
ViewHelper will return `null`.

Go to the source code of this ViewHelper: [SlotViewHelper.php (GitHub)](https://github.com/TYPO3/Fluid/blob/main/src/ViewHelpers/SlotViewHelper.php).
