Plugins can include field and/or input level templates to support special UI rendering or non-standard property types. Just include the templates in the plugin’s grails-app/views directory as described in the Customizing Field Rendering section.

In order to be performant, the Fields plugin caches field template lookup results by default. This makes it possible to perform the time-consuming template path resolutions only once during the runtime of the application.

When template caching is active, only the first page renderings are slow, subsequent ones are fast.

Due to the flexibility needed during template development, this feature can be disabled so it would be possible to recognize newly added field templates without restarting the application. As a result, with bigger webpages, containing a lot of fields, rendering may be fairly slow in development (depending on the number of fields on the page).
