# Create a phantom node which takes up no space with forest 2.1.5

It is basically the same question as Forest: Create phantom node which takes up no space? but the solution offered there does not work with forest 2.1.5. I want the phantom S not to take space. I tried setting the baseline to the phantom node, but this did not have any effect.

\documentclass{article}
\usepackage{forest}
\useforestlibrary{linguistics}

\begin{document}
\noindent

This is some very informative text, that is very informative.\\
\begin{forest}
[\phantom{S}
[S, no edge, baseline
[NP,name=np11
[he]]
[VP, name=vp1
[V,name=v1    [knows]]]]
[S, no edge, name=s2
[V, name=vcoord, no edge [and, name=and, no edge]]
[VP
[V,name=v2 [loves]]
[NP, name=np22 [this record, roof]]]]]
\draw (s2.south)--(np11.north)
(vp1.south)--(np22.north);
\draw[thick] (vcoord.south)--(v1.north)
(vcoord.south)--(v2.north)
(vcoord.south)--(and.north);
\end{forest}

\end{document}

• I'm not sure what the output should look like, but load forest with [linguistics] as a package option rather than \useforestibrary. Does that solve the problem? – Alan Munn Aug 12 at 15:49
• Right now the figure takes the same space as if the \phantom{s} would be visible. Loading the package with an option produces different output. Surprising! But the problem does not disappear. – Stefan Müller Aug 12 at 16:04

The solution is to use the phantom key of forest rather than the \phantom macro, which just makes the S invisible.
