ListElement ​

Repeats other elements.

Basic Usage ​

<ListElement> component can be used in a <Vueform> component to repeat a single element:

vue
<template>
  <Vueform>
    <ListElement name="list">
      <template #default="{ index }">
        <TextElement
          :name="index"
          placeholder="To-do"
        />
      </template>
    </ListElement>
  </Vueform>
</template>

It can also be used to render multiple elements in an <ObjectElement>:

vue
<template>
  <Vueform>
    <ListElement name="list">
      <template #default="{ index }">
        <ObjectElement
          :name="index"
          :label="`To-do #${index+1}`
        ">
          <TextElement
            name="todo"
            placeholder="To-do"
          />
          <CheckboxElement
            name="ready"
            text="Ready"
            add-class="-mt-2"
          />
        </ObjectElement>
      </template>
    </ListElement>
  </Vueform>
</template>

Important: the element in <ListElement> must always use index as name from slot scope.

Configuration options can be passed over as regular component props. Check out Options section for available configuration options.

Options ​

Find below the list of options that can use to configure ListElement component. Options can be passed to the component via props in inline templates, or in the element's object when using schema.

element ​

  • Type: object
  • Default: null
vue
<ListElement :element="{ type: 'text', placeholder: 'To-do' }"... />

Defines a single element that gets repeated within the list. It can by any type of element except group.

Alternatively you can use the #default slot to render a single element:

template
<ListElement name="todos">
  <template #default="{ index }">
    <TextElement :name="index" placeholder="To-do (inline)" />
  </template>
</ListElement>

Important: When using inline element, its name has to equal to default slot's index scope.

If you would like to repeat multiple elements use object.

object ​

  • Type: object
  • Default: null
template
<ListElement :object="{
  label: 'To-do',
  schema: {
    todo: { type: 'text', placeholder: 'To-do' },
    ready: { type: 'checkbox', text: 'Ready' },
  }
}" ... />

Defines an ObjectElement with multiple elements that gets repeated within the list. The object can contain any options an ObjectElement would and will be applied to each instance.

Alternatively you can use the #default slot to render multiple elements in an ObjectElement:

template
<ListElement name="todos">
  <template #default="{ index }">
    <ObjectElement :name="index">
      <TextElement name="todo" placeholder="To-do (inline)" />
      <CheckboxElement name="ready" text="Ready" />
    </ObjectElement>
  </template>
</ListElement>

Important: When using inline object, its name has to equal to default slot's index scope.

initial ​

  • Type: number
  • Default: 1
vue
<ListElement :initial="3" ... />

The initial number of items the list should have.

min ​

  • Type: number
  • Default: -1
vue
<ListElement :min="2" :initial="3" ... />

The minimum number of elements the list should have. List items can't be removed if their number is <= min. The -1 value turns off the requirement.

max ​

  • Type: number
  • Default: -1
vue
<ListElement :max="4" :initial="3" ... />

The maximum number of elements the list can have. Can't add new items if their number is >= max. The -1 value turns off the limit.

addText ​

  • Type: string
  • Default: locale.elements.list.add
vue
<ListElement add-text="Add to-do" ... />

The label of add button.

sort ​

  • Type: boolean
  • Default: false
vue
<ListElement :sort="true" :default="[1,2,3]" ... />

Whether the list elements can be sorted.

controls ​

  • Type: object
  • Default: {
    "add": true,
    "remove": true,
    "sort": true
    }
vue
<!-- Can't add --->
<ListElement :sort="true" :controls="{ add: false }" ... />

<!-- Can't remove --->
<ListElement :sort="true" :controls="{ remove: false }" ... />

<!-- Can't sort --->
<ListElement :sort="true" :controls="{ sort: false }" ... />

Defines the available list controls in an object. Object properties:

  • add - enables/disables adding a new item
  • remove - enables/disables removing items
  • sort - enables/disables sorting when sort is enabled

storeOrder ​

  • Type: string
  • Default: null
vue
<ListElement :sort="true" store-order="order" :object="{
  schema: {
    name: { type: 'text', floating: 'Name', columns: 9 },
    order: { type: 'text', columns: 3 },
  }
}" @mounted="el$ => el$.load([
  { name: 'John', order: 1 },
  { name: 'Stephen', order: 2 },
  { name: 'Mary', order: 3 },
])" ... />

The name of the element that stores the order value when using sort and object. The element is recommended to be HiddenElement.

order ​

  • Type: string
  • Default: null
template
<!-- Using `element` --->
<ListElement order="asc" :element="{
  type: 'text',
  placeholder: 'To-do',
}" @mounted="el$ => el$.load([3,1,2])" ... />

<!-- Using `object` and `orderBy` --->
<ListElement order="desc" order-by="age" :object="{
  schema: {
    name: { type: 'text', floating: 'Name', columns: 6 },
    age: { type: 'text', floating: 'Age', columns: 6 },
  }
}" @mounted="el$ => el$.load([
  { name: 'John', age: 17, },
  { name: 'Stephen', age: 32, },
  { name: 'Mary', age: 25, },
])" ... />

Automatically sorts the list when data is loaded. Possible values: 'asc|desc'.

If the list is using an element it will be sorted based on its value.

If the list is using an object it should be used in conjunction with orderBy which defines the name of the object property that contains the order.

orderBy ​

  • Type: string
  • Default: null
vue
<ListElement order="desc" order-by="age" :object="{
  schema: {
    name: { type: 'text', floating: 'Name', columns: 6 },

<!-- Group 2 - only if field1 != 'show' -->
<ListElement" :conditions="[['field1', '!=', 'show']]" ... />

<!-- Group 3 - only if field1 == 'show' -->
<ListElement :conditions="[
  (form$, el$) => form$.el$('field1')?.value === 'show'
]" ... />

Shows or hides an element based on the provided conditions.

If an element's conditions are unmet the element will be hidden and its available property will become false. If hidden, its value will not be part of requestData.

Conditions can be provided as an array, where each item has to be either an array or a function. The element will only become available if all the conditions are fulfilled.

If a condition is provided as an array, the first value must be the path of an other field which value should be watched. The second is an operator that defines the type of comparison. The third is the expected value of the other field.

vue
<ListElement name="field" :conditions="[['other_field', '==', 'expected_value']]" ... />

Hint: In case you want to check for equality you might leave the operator and pass the expected value as the second param:

vue
<ListElement name="field" :conditions="[['other_field', 'expected_value']]" ... />

Available operators:

  • == - expect equality
  • != - expect inequality
  • > - expect the other element's value(s) to be higher
  • >=- expect the other element's value(s) to be higher or equal
  • < - expect the other element's value(s) to be lower
  • <= - expect the other element's value(s) to be lower or equal
  • ^ - expect the other element's value to start with
  • $ - expect the other element's value to end with
  • * - expect the other element's value to contain
  • in - expect to be among an array of values
  • not_in - expect not to be among an array of values
  • today - expect to be today
  • before - expect to be before a date (value can be a YYYY-MM-DD date string or today)
  • after - expect to be after a date (value can be a YYYY-MM-DD date string or today)

The expected value can also be defined as an array in which case any of its values will fulfill the condition.

Conditions can be defined with OR relation or as function. Learn more about conditions here.

columns ​

  • Type: object|string|number
  • Default: null
vue
<ListElement label="Label" :columns="{ container: 12, label: 3, wrapper: 12 }" ... />

Sets the size of the container, label and wrapper using the theme's grid system, where the:

  • container is the outermost DOM that contains both label and wrapper
  • label contains the label
  • wrapper contains the list.
container: 12
label: 3
wrapper: 12

The value of container defines the size of the element's container. 12 will result in full width, 6 in half, 4 in third and so on.

The value of label defines the amount of space the label should take up within the container. If the container is 12 and label is 6 the label is going to take up half the space and the list will the other half (which is calculated automatically). If the container is 6 and label is 6, the label will only take up one forth and the list the rest. In case the label has full width (12) the list will also take up full space instead of becoming zero.

The value of wrapper defines the size of the list wrapper within the space left for it in the container after subtracting the size of the label. If the container is 12 and label is 4 the space left for the list is 8. In this case if the wrapper value is 12 it will take up the full space left for it (which is 8) while if it is changed to 6 it will only take up half the space left for it (4):

vue
<ListElement label="Label" :columns="{ container: 12, label: 4, wrapper: 12 }" ... />
<ListElement label="Label" :columns="{ container: 12, label: 4, wrapper: 6 }" ... />

Note that while the size of the list wrapper changes, the size of extras like a description or error won't be limited to the wrapper's space. Instead it will take up the full space in the container left after subtracting the size of the label:

vue
<ListElement
  label="Label"
  :columns="{ container: 12, label: 4, wrapper: 6 }" 
  description="Lorem ipsum dolor sit amet, consectetur adipiscing elit"
... />

You can set the value of columns as a number in which case the container will receive its value without affecting the default settings of label and wrapper:

vue
<ListElement label="Label" :columns="6" ... /> <!-- { container: 6, label: 3, wrapper: 12 } -->

You can as well define column values for different breakpoints using the theme system's breakpoints like sm, md, etc. as keys:

vue
<ListElement label="Label" :columns="{
  xs: { container: 12, label: 12, wrapper: 12 },
  sm: { container: 12, label: 4, wrapper: 12 },
  md: 12,
  lg: { container: 12, label: 2, wrapper: 12 }
}" ... />

Default column sizes can be defined globally in vueform.config.js or on form level using columns.

inline ​

  • Type: boolean
  • Default: false
vue
<ListElement :inline="true" ... />

Renders the element and all of its components in a single <span> without applying columns.

size ​

  • Type: string
  • Default: undefined
vue
<ListElement size="sm" ... />
<ListElement ... /> <!-- Default size: 'md' -->
<ListElement size="lg" ... />

The size of the element and its child components.

view ​

  • Type: string
  • Default: undefined
vue
<ListElement view="alt" ... />

  • Default: {}
vue
<script>
import { Vueform, useVueform } from '@vueform/vueform';
import CustomDescriptionSlot from 'path/to/CustomDescriptionSlot.vue';
