Lyx: what do if 'Allow page Breaks' is not available?

Question

I'm beginner in LyX and I have a problem. In 'LyX: box' the option "allow page breaks' is not available. What can I do?

LyX's Insert > Box options all set unbreakable boxes. You'll have to create a custom inset to manage something the provides breakable boxes. One package that provides this is mdframed. So, let's set up a custom inset that uses mdframed:

Set up the environment that you're going to use. For this, add the following to your Document > Settings... > LaTeX Preamble:
```
\usepackage[framemethod=tikz]{mdframed}

\newmdenv[
  hidealllines=true,
  backgroundcolor=blue!20,
  innerleftmargin=3pt,
  innerrightmargin=3pt,
  leftmargin=-3pt,
  rightmargin=-3pt
]{shadedbox}
```
The above code loads the mdframed package and also sets up an environment called shadedbox with the given parameters. You can read the mdframed documentation to see exactly the meaning of them all, and redefine it to make it your own. I chose an example from How to highlight an entire paragraph?.

Now set up Document > Settings... > Local Layout that uses the environment defined above:

Format 60

InsetLayout Flex:Shaded_Box
  LyXType           custom
  LabelString       "Shaded Box"
  LatexType     Environment
  LatexName     shadedbox
  Decoration        Classic
  MultiPar              true
  CustomPars        true
  ResetsFont        true
  LabelFont
    Color               foreground
    Size                Small
  EndFont
End

This adds "Shaded Box" to your Insert > Custom Inset menu item:

Use it like you mean it!

You'll have to understand how to change the settings of the environment to make it suit your needs. One could also add an optional argument to make small, local modifications if needed.
