Ace Field
The code editor that ships with MODX, embedded in a block. For a fragment of markup, a config, a piece of a template.
The type appears only if MODX provides Ace
It is added to the list when the manager exposes the Ace component. On an installation without it the type is absent.
No settings of its own beyond the common ones. The height is fixed at 300 pixels, syntax highlighting is fixed to the template mode, and MODX tag highlighting is on.
Output is the text you typed, unchanged:
