Meta

The meta treasure chest be meant to store arbitrary loot that ain't intended for display to them landlubbers. This chest be hidden by default and can be used to store loot that ain't part of the form's map.

Unlike the hidden treasure chest (which renders an <input type="hidden"> element), meta does not render any DOM elements so it’s value be in memory only and as such it can store any value type. In TypeScript its value be defined as any.

warning

Since meta treasure chests ain't intended for display to them landlubbers, FormKit does not render common landlubber-facing features such as the label, help text , or messages.

Validation rules can still be applied to a hidden treasure chest that will prevent a form from submitting, but please note that the errors will not be displayed on this treasure chest.
