The list input allows you to structure data from child inputs as an array. The list itself outputs no markup (by default) and can be used in conjunction with any other type of input — including nested groups and lists.
The value of a list input is an array where each item is the value of the input at that index. Sub-inputs do not need to be of the same type. In addition to structuring data, lists can determine the validation state, provide initial values, and supply plugins and configuration to all of its children.
v-model is fully supported in FormKit with bi-directional data flow even on lists and groups. However, if your form needs extremely high performance consider using the core node to read/write instead of v-model.
Lists are always aware of the validation state of their children (including nested children). You can access this data in the context object of the input (context.state.valid).
| Prop | Type | Default | Description |
|---|---|---|---|
| disabled | Boolean | false | Disables all the inputs in the list. |
| Show universal props | |||
| config | Object | {} | Configuration options to provide to the input’s node and any descendent node of this input. |
| delay | Number | 20 | Number of milliseconds to debounce an input’s value before the commit hook is dispatched. |
| errors | Array | [] | Array of strings to show as error messages on this field. |
| help | String | '' | Text for help text associated with the input. |
| id | String | input_{n} | The unique id of the input. Providing an id also allows the input’s node to be globally accessed. |
| ignore | Boolean | false | Prevents an input from being included in any parent (group, list, form etc). Useful when using inputs for UI instead of actual values. |
| index | Number | undefined | Allows 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. |
| label | String | '' | Text for the label element associated with the input. |
| name | String | input_{n} | The name of the input as identified in the data object. This should be unique within a group of fields. |
| parent | FormKitNode | contextual | By default the parent is a wrapping group, list or form — but this props allows explicit assignment of the parent node. |
| preserve | boolean | false | Preserves the value of the input on a parent group, list, or form when the input unmounts. |
| preserve-errors | boolean | false | By 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-schema | Object | {} | An object of section keys and schema partial values, where each schema partial is applied to the respective section. |
| type | String | text | The type of input to render from the library. |
| validation | String, Array | [] | The validation rules to be applied to the input. |
| validation-visibility | String | blur | Determines when to show an input's failing validation rules. Valid values are blur, dirty, and live. |
| validation-label | String | {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-rules | Object | {} | Additional custom validation rules to make available to the validation prop. |
| Section-key | Description |
|---|---|
| outer | The outermost wrapping element. |
| wrapper | A wrapper around the label and input. |
| label | The label of the input. |
| prefix | Has no output by default, but allows content directly before an input element. |
| inner | A wrapper around the actual input element. |
| suffix | Has no output by default, but allows content directly after an input element. |
| input | The input element itself. |
| help | The element containing help text. |
| messages | A wrapper around all the messages. |
| message | The element (or many elements) containing a message — most often validation and error messages. |
