Additional info to Forest Tree & fit tree to page

foresttrees

I'm trying to reproduce the image below.
As you can see on the left margin has some info: Channel, Code Type, Sender etc. aligned with descendants.

Also, on Repertoire of codes and channels > visual > + verbal has additional info placards, banner etc.

The same info is also on -verbal > figure > + durative
a.s.o

Here is what I tried

this is the first time I'm using forest package

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{backgrounds}
\usepackage[linguistics]{forest}
\begin{document}


\begin{forest}% should be fit to page
  [Repertoriul codurilor și al canalelor
    [vizual % this is CHANEL
      [+ verbal % this is Code type
        [,phantom
          [pancarde % has to be aditional info to the tree
          [banere   % has to be aditional info to the tree
          [etc.]    % has to be aditional info to the tree
          ]
          ]
        ]
      ]
      [- verbal

For the information on the side, you had the right idea, but at the wrong level of the tree. You need to make a phantom branch as the leftmost branch of the tree, and then for subsequent labels specify no edge to remove the line between nodes.

For the extra information below the terminal nodes, you can just use \\ to create new lines in a node label. Since you're loading the linguistics library, nodes are already specified with the align=center key, so node labels can have \\ inside them. (In my previous version, I made these nodes with no edge because I thought they were uniformly at the bottom row of the tree, but in retrospect, I don't think this is the best way to do it.)

To more faithfully reproduce the tree in your image, I've also added an explicit tier=fig key to each of the nodes so that all of the "Sender" level nodes appear at the same level.

Unless you want to make the font smaller, there's no good way to make this tree more compact and have it fit on the page in portrait mode, with the default page margins, and it barely fits with 1cm margins on an A4 page, so I would recommend using the lscape package and its landscape environment to put the tree in landscape orientation.

\documentclass[a4paper]{article}
\usepackage[utf8]{inputenc} % not needed with recent TeX distributions
\usepackage{tikz}
\usetikzlibrary{backgrounds}
\usepackage[linguistics]{forest}
\usepackage{lscape}
\begin{document}

\begin{landscape} % use this environment to make the tree appear in landscape mode

[Tex/LaTex] Unbalanced binary tree with forest

There are various things you might mean by 'missing nodes'. A Minimal Working Example of the kind of tree you have, together with an explanation of how you wish to adapt it would be invaluable.

The following example shows three things you might have in mind:

Missing nodes

Node 2 is missing in a first sense: the branch simply continues without stopping to make the node. This creates an 'unbalanced' tree - the angles of the left and right branches are different.

This effect is achieved by altering the distance of node 4's level using l*=2 which doubles it.

Node 6 is missing in a second sense: it is simply empty. It is treated in every way as a proper node but there is no content.

This is straightforward - {} just provides empty content.

Node 9 is missing in a third sense: it causes a gap in the entire structure of branches and nodes. This isolates its children, 17 and 18 from the remainder of the tree.

This uses .phantom style demonstrated in NightRa's answer.

The code:

\documentclass{standalone}
\usepackage{forest}

\begin{document}
\begin{forest}
  [1, for tree=draw
    [4, l*=2
      [7
        [13]
        [14]]
      [8
        [15]
        [16]]
    ]
    [3
      [5
        [,.phantom
          [17]
          [18]]
        [10
          [19]
          [20]]
      ]
      [{}
        [11
          [21]
          [22]]
        [12
          [23]
          [24]]
      ]
    ]
  ]

[Tex/LaTex] Forest: Adjust tree edge path

You are loading the edges library but not actually using it, which is odd since this is precisely the kind of style it supports. Moreover, it does away with the need to fake the structure of the tree, allowing you to keep the intuitive parent-child relationships in your mark-up.

In this case, the folder style is the obvious choice, at least ignoring its misleading name. The only issue really is that it doesn't do the right thing when it applies only beyond a certain level and, because it tries to do the right thing in a clever way, you have to override it late in the processing of the tree.

For example,

\documentclass[border=10pt]{standalone}
\usepackage[edges]{forest}
\usetikzlibrary{shadows,arrows.meta}
\tikzset{
  parent/.style={align=center,text width=4cm,fill=gray!50,rounded corners=2pt},
  child/.style={align=center,text width=2.5cm,fill=gray!20,rounded corners=6pt},
  grandchild/.style={fill=white,text width=2.3cm}
}
\begin{document}
\begin{forest}
  for tree={%
    thick,
    drop shadow,
    node options={
      draw,
      font=\sffamily
    },
    edge={
      semithick,
      -Latex
    },
    where level=0{
      parent,
      l sep'=0.8cm,
      s sep'=1.0cm,
    }{
      folder,
      grow'=0,
    },
    where level=1{
      minimum height=1cm,
      child,
      l sep=7.5mm,
      for descendants={%
        grandchild,
        minimum height=0.6cm,
      },
      for children={
        before computing xy={s+=5mm},
      }
    }{},
  }
  [\large Long text with line break%
    [\textbf{Test 1} \\ with a lot of subtext%
      [Topic]
      [Long topic with line break]
      [Topic]
    ]
    [\textbf{Test 2} \\ with a lot of subtext%
      [Topic]
      [Long topic with line break]
      [Topic]

    [\textbf{Test 3} \\ with a lot of subtext%
      [Topic]
      [Long topic with line break]
      [Topic]
    ]
    [\textbf{Test 4} \\ with a lot of subtext%
      [Topic]
      [Long topic with line break]
      [Topic]
    ]
  ]
