Question: I'm working on an ASP.NET MVC project which uses the [MarkdownDeep Editor](http://www.toptensoftware.com/markdowndeep/editor) to add a rich editor on top of a basic markdown input textbox (very similar to the Stackoverflow editor window).

Generally it works great. However, in certain scenarios, I would like to disable the preview window. This is automatically generated below the textarea by MDD. Can this be disabled?

Just to be clear, I know I can use CSS to *hide* the preview. But on some devices it's slow and makes typing painful. I want to entirely *turn off* that feature. I don't see anything in the docs other than how to customize the preview.

Any ideas?

Answer: 
In the [docs](http://www.toptensoftware.com/markdowndeep/editor) it specifically mentions that it is recommended that you have the div preview already in your document because it will be created if it isn't found and consequently, could could a visible page refresh if any re-layout has to occur.

Thus from the sounds of this, and that there doesn't appear to be any option to turn it off in the [API](http://www.toptensoftware.com/markdowndeep/api) page I would say no, it's not possible.
I know this is old, but I was looking for something else on mdd. I recently had this same requirement.
Just comment out the code 

```
// Update the DOM
if (this.m_divHtml)
    this.m_divHtml.innerHTML=output;

```

in MarkdownDeepEditor.js
