GridElement ​

<GridElement :cols="4" ... />

The number of columns the grid should have.

<GridElement :rows="4" ... />

The number of rows the grid should have.

The grid option defines the following aspects:

• The content of cells
• Colspans and rowspans
• Horizontal and vertical alignment of cells

The grid option is an array where each item represents a row.

Each row is also an array of items representing cells (or columns).

Cells can have one of the following values:

• null - Represents an empty cell
• string - Contains text content
• object - Defines an element schema (e.g., { type: 'text', name: 'first_name' })
• array - Allows additional properties like colspan, rowspan, align, and valign.

Defining Empty Cells ​

<GridElement :presets="['grid-table']" :grid="[
  [null,null],
  [null,null]
] ... />

Write Text to Cells ​

<GridElement :presets="['grid-table']" :grid="[
  ['A','B'],
  ['C','D'],
] ... />

The cell content can also include HTML.

Using Elements in Cells ​

<GridElement :presets="['grid-table']" :grid="[
  [
    { type: 'text', name: 'a', placeholder: 'A' },
    { type: 'select', items: [1,2,3], name: 'b', placeholder: 'B' },
  ],
  [
    { type: 'date', name: 'c', placeholder: 'C' },
    { type: 'slider', name: 'd' },
  ]
] ... />

Ensure each input has a name property. Otherwise, cell names will default to {gridName}_{row}_{col}.

Defining Rowspan / Colspan ​

<GridElement name="grid_grid5" :presets="['grid-table']" :cols="3" :rows="3" :grid="[
  [
    ['A', 0, 2], // rowspan: 2
    [{ type: 'text', placeholder: 'Write here...' }, 2, 0], // colspan: 2
  ],
  [
    'C',
    'D',
  ],
  [
    'E',
    'F',
    'G',
  ],
] ... />

Use our drag and drop form builder for creating complex grid layouts with ease.

Horizontally / Vertically Align Cells ​

<GridElement name="" :presets="['grid-table']" :grid="[
  [
    ['A', 1, 1, 'center', 'middle'], // center horizontally and vertically
    'B1<br>B2<br>B3'
  ],
  [
    'C',
    'D',
  ],
] ... />

The horizontal and vertical alignment are only applied to text cells.

<GridElement align="center" ... />

The default horizontal align of the cells when they are texts. Possible values: left, center, right or justify.

<GridElement valign="middle" ... />

The default vertical align of the cells when they are texts. Possible values: top, middle, bottom or baseline.

<GridElement :widths="[null, '2fr']" ... />

The widths of columns in the order of columns as an array. Each value can be number or string. If it is numeric it will be converted to px. The value will be used in the grid-template-columns CSS property. If a value is null it will be 1fr (1 fraction or unit).

<GridElement :min-width="600" ... />

The minimum width of the grid. If the value is a number it will be converted to px.

<GridElement :max-width="320" ... />

The maximum width of the grid. If the value is a number it will be converted to px.

<GridElement scrollable ... />

Whether the grid should become scrollable when the cells would overflow. Enabling this feature will clip absolute positioned content (eg. select dropdowns, bottom slider tooltips) so try avoid using it when possible.

<GridElement :presets="['grid-table']" col-header ... />

Whether the first row should become column header when using table view (presets: ['grid-table']).

<GridElement :presets="['grid-table']" row-header ... />

Whether the first column should become row header when using table view (presets: ['grid-table']).

<GridElement name="element" ... />

Sets the element's name and the name attribute of the grid.

<GridElement id="field-id" ... />

Sets the id attribute of the grid.

Sets a label for the element. Can be defined as a string, a Vue component object with a render function or as a function that receives el$ as its first a param.

Can also be defined via #label slot.

<GridElement label="Info" info="Info" ... />

Renders an ElementInfo component next to the element's label. By default the icon shows the value of info when hovered, which can contain plain text or HTML. The element needs to have a label defined in order for info to be rendered.

Can be also defined via #info slot.

<GridElement label="Top" info="Top" info-position="top" ... />
<GridElement label="Right" info="Right" info-position="right" ... />
<GridElement label="Left" info="Left" info-position="left" ... />
<GridElement label="Bottom" info="Bottom" info-position="bottom" ... />

Sets the position of the info tooltip.

Can be also defined via #info slot.

<GridElement description="Lorem ipsum dolor sit amet" ... />

Renders the contents of description prop in the ElementDescription component below the grid. It can contain plain text or HTML.

Can be also defined via #description slot.

<GridElement before="Before" ... />

Renders the contents of before in a ElementText component before the grid. It can contain plain text or HTML.

Can be also defined via #before slot.

<GridElement description="Description" between="Between" ... />

Renders the contents of between in a ElementText component between the grid and the description. It can contain plain text or HTML.

Can be also defined via #between slot.

<GridElement description="Description" after="After" ... />

Renders the contents of after in a ElementText component after the description and error. It can contain plain text or HTML.

Can be also defined via #after slot.

<GridElement :default="{
  name: 'John Doe',
  time: '13:11',
  select: 1,
  tag: ['Nuxt']
}" ... />

Sets the default value of children.

<GridElement :format-data="(n, v) => ({[n]: /* transformed value */ })" ... />

Formats the element's requestData.

The first param is the element's name, the second is the value. The return value should be an object, which only contains one item with the element's name as key and the transformed value as value.

<GridElement :format-load="(v) => /* transformed value */" ... />

Formats the data being loaded to the element when using load(data, format: true). It receives the value being loaded to the element as its first param and should return the formatted value of the element.

<GridElement :submit="false" ... />

If set to false the element's data will not be included in requestData and will not be submitted.

<GridElement rules="custom_rule" ... />
<GridElement :rules="['custom_rule']" ... />

The validation rules to be applied for the element.

The list of rules can be defined as a string separated by | or as an array, where each item should be a single validation rule.

<GridElement field-name="Field name" rules="custom_rule" ... />

Sets the name of the field in validation rule messages.

<GridElement name="messages" :messages="{ custom_rule: 'Please fill in one of the fields' }" ... />

Overrides the default messages for the element's validation rules. The value is an object where each key is the name of a validation rule and the value is the error message that will be displayed when the rule fails.

You can override validation messages on form level with messages.

<GridElement :display-errors="false" ... />

Whether element errors should be displayed.

<!-- field1 - type 'show' -->
<TextElement name="field1" ... />

<!-- field2 - only if field1 == 'show' -->
<GridElement name="field2" :conditions="[['field1', 'show']]" ... />

<!-- field3 - only if field1 != 'show' -->
<GridElement name="field3" :conditions="[['field1', '!=', 'show']]" ... />

<!-- field4 - only if field1 == 'show' -->
<GridElement name="field4" :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.

<GridElement 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:

<GridElement 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.

<GridElement 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 grid.

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 grid 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 grid the rest. In case the label has full width (12) the grid will also take up full space instead of becoming zero.

The value of wrapper defines the size of the grid 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 grid 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):

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

Note that while the size of the grid 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:

<GridElement
  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:

<GridElement 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:

<GridElement 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.

<GridElement :inline="true" ... />

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

<GridElement size="sm" ... />
<GridElement ... /> <!-- Default size: 'md' -->
<GridElement size="lg" ... />

The size of the element and its child components.

<GridElement view="alt" ... />

The name of the view to be used for the element and by default for its child components. If undefined the default view will be used. Child component views can be overridden with views option.

  }
}" ... />

Adds classes to any component's class names. The classes can have string or array values. When Vue style classes are used object values must be wrapped in an array.

Conditional classes can be passed as a function with form$ param, eg.:

<GridElement :add-classes="(form$) => ({
