Inputs

Meta

Renderless Input

The meta input does not render any output to the DOM. It is used exclusively for including arbitrary data in your forms without displaying it to end users.

The meta input is meant to store arbitrary data that is not intended for display to end users. This input is hidden by default and can be used to store data that is not part of the form's schema.

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

Basic example

<script setup>import { ref } from 'vue'const extraData = {  hair: 'gold',  eyes: 'blue',  weight: '215lb',  height: '6ft 3in',  hands: 'tiny',  cool: false}</script><template>  <FormKit type="form" :actions="false" #default="{ value }">    <FormKit name="name" label="Name" />    <FormKit type="meta" name="metaDetails" :value="extraData" />    <pre wrap>{{ value }}</pre>  </FormKit></template>
{}

Props & Attributes

The meta input has no unique props but can make use of the following universal FormKit props.

PropType Default Description
configObject{}Configuration options to provide to the input’s node and any descendent node of this input.
delayNumber20Number of milliseconds to debounce an input’s value before the commit hook is dispatched.
dirtyBehaviorstringtouchedDetermines how the "dirty" flag of this input is set. Can be set to touched or comparetouched (the default) is more performant, but will not detect when the form is once again matching its initial state.
errorsArray[]Array of strings to show as error messages on this field.
helpString''Text for help text associated with the input.
idStringinput_{n}The unique id of the input. Providing an id also allows the input’s node to be globally accessed.
ignoreBooleanfalsePrevents an input from being included in any parent (group, list, form etc). Useful when using inputs for UI instead of actual values.
indexNumberundefinedAllows an input to be inserted at the given index if the parent is a list. If the input’s value is undefined, it inherits the value from that index position. If it has a value it inserts it into the lists’s values at the given index.
labelString''Text for the label element associated with the input.
nameStringinput_{n}The name of the input as identified in the data object. This should be unique within a group of fields.
parentFormKitNodecontextualBy default the parent is a wrapping group, list or form — but this props allows explicit assignment of the parent node.
prefix-iconString''Specifies an icon to put in the prefixIcon section.
preserveBooleanfalsePreserves the value of the input on a parent group, list, or form when the input unmounts.
preserve-errorsBooleanfalseBy default errors set on inputs using setErrors are automatically cleared on input, setting this prop to true maintains the error until it is explicitly cleared.
sections-schemaObject{}An object of section keys and schema partial values, where each schema partial is applied to the respective section.
suffix-iconString''Specifies an icon to put in the suffixIcon section.
typeStringtextThe type of input to render from the library.
validationString, Array[]The validation rules to be applied to the input.
validation-visibilityStringblurDetermines when to show an input's failing validation rules. Valid values are blur, dirty, and live.
validation-labelString{label prop}Determines what label to use in validation error messages, by default it uses the label prop if available, otherwise it uses the name prop.
validation-rulesObject{}Additional custom validation rules to make available to the validation prop.
valueAnyundefinedSeeds the initial value of an input and/or its children. Not reactive. Can seed entire groups (forms) and lists..

Sections

The meta input renders no output to the DOM so there are no sections to display. The meta input is used exclusively for including arbitrary data in your forms without displaying it to end users.
