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 contains one item with the element's name as key and an object containing the transformed value for each language key (eg. en) as value.

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

If you only want debounce for a specific rule, you can use: rules="required|email:debounce=500"

<TTextareaElement rules="required" :messages="{ required: 'Please fill in' }" ... />

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.

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

<!-- field4 - only if field1 == 'show' -->
<TTextareaElement 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.

<TTextareaElement 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:

<TTextareaElement 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.

<TTextareaElement 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 textarea.

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

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

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

Note that while the size of the textarea 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:

<TTextareaElement
  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:

<TTextareaElement 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:

<TTextareaElement 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.

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

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

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

The size of the element and its child components.

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

    classname: [{'class-value': true}],
  }
}" ... />

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.:

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

    ],
