Markdown
The markdown component allows to edit and display Markdown formatted text.
The item part markdown can be used in edit and read mode (display mode):
<item name="invoice.summary"
type="custom"
path="markdown"
label="Summary" />

In case readonly is set to true the component displays the content as HTML-
<item type="custom"
path="spaceref"
label="Department:"
readonly="true" />

The component is based on the Marked Java Script Library.
