Widgets

The Axelor Open Platform web application provides some built-in widgets. These widgets are used to represent data in form view.

All the widgets represents a domain object field and can override all the properties (min, max, required, readonly etc.) of underlying fields.

Following widgets have been implemented:

String

The string widget represents the string data type. It’s used for simple string fields.

<field name="string"/>

Email

This widget can be used for string fields to enter email address.

<field name="email" widget="email" />

The input value will be validated to ensure user provides valid email id.

Url

This widget can be used for string fields to enter url value.

<field name="website" widget="url" />

Phone

This widget can be used for string fields to enter phone values.

<field name="phone" widget="phone" />

The phone widget uses the International Telephone Input plugin. All x- prefixed attributes are passed to the plugin. Here are a few useful options:

  • x-placeholder-number-type - number type to use for the placeholder, such as MOBILE (default) or FIXED_LINE (list of all possible keys)

  • x-custom-placeholder - JSON of custom placeholders by country code

  • x-initial-country - initial country selection by specifying its country code (default is browser-dependent)

The number widget is used for integer and decimal data fields.

Number widget has specials attributes:

  • min: lowest bound of the value

  • max: upper bound of the value

  • x-scale: scale of the decimal value (total number of digits in decimal part). It accepts an integer for a fix scale, or a field name for a dynamic evaluation.

  • x-precision: precision of the decimal value (total number of digits).

<field name="integer" widget="Integer"/>
<field name="decimal" widget="Decimal" x-scale="2" x-precision="18"/>
<field name="decimal" widget="Decimal" x-scale="currency.decimalPlaces" x-precision="18"/>

Rating

The rating widget is used for integer/long/decimal data fields. It provides ability to collect measurable opinions/experiences/feedbacks/…​

Rating widget supports following attributes :

  <field name="product" />
  <field name="quantity" />
  <field name="price" />
</panel-related>

You can also display the values as repeated viewer or editor using normal field widget:

</selection>

RefSelect

Sometimes we need to reference a record from different types. For example, in an Email, we may have to give reference to an Invoice or SaleOrder or even a Contact. The standard ManyToOne field can’t work here as it can only refer single type.

The RefSelect widget can be used in such cases. In order to use RefSelect, we require two fields in target object and a selection of types.

<entity ...>
  ...
  <string name="reference" /> (1)
  <integer name="referenceId" /> (2)
</entity>
1 - will store the reference object type name
2 - will store the reference record id

and a selection of types:

<selection name="my.reference.select">
  <option value="com.axelor.sale.db.Order">SaleOrder</option> (1)
  <option value="com.axelor.contact.db.Contact"
    data-domain="self.email LIKE '%gmail%'"
    data-grid="my-custom-grid-view">Contact</option> (2)
</selection>
1 - define selection option with fully qualified type name as value
2 - you can define extra attributes using data- prefix

and we can use the reference widget like this:

<form ...>
  ...
  <field name="reference" selection="my.reference.select" widget="RefSelect" />
</form>
Use data-grid or data-form attributes to specify different views

In edit mode, this widget is the same as RefSelect. But in readonly mode, it only displays the link to the record (the type is not displayed).

Example usage from TeamTask:

<field name="relatedModel"
  title="Link"
  colSpan="12"
  widget="ref-link"
  selection="team.task.links"
  x-related="relatedId" />

In edit mode, this widget is used as string field input and we can enter interpolate string value. But in readonly mode, it displayed as Image widget with src link to that input value.

EvalRefSelect

This widget can be used to select reference value depending on dynamic target model value. The following attributes should be provided:

  • x-eval-target: expression to find target model

  • x-eval-target-name: expression to find target model name field

  • x-eval-value: expression to get/set reference value (id)

  • x-eval-title: expression to get/set reference title (name value)

Example usage from MetaJsonField:

<field name="contextFieldValue"
  widget="eval-ref-select"
  x-eval-target="contextFieldTarget"
  x-eval-target-name="contextFieldTargetName"
  x-eval-value="contextFieldValue"
  x-eval-title="contextFieldTitle" />

RefText

This widget can be used to select string field value of a record.

  • x-target: target model

  • x-target-name: target model name field

  • x-target-search: optional additional field value in selection list, displayed as x-target-name (x-target-search)

  • x-domain: optional domain filter on target model

Example where we select model name of meta model:

<field name="model" required="true" widget="ref-text"
  x-target="com.axelor.meta.db.MetaModel"
  x-target-name="fullName" />

Example where we select name of meta view, add module name in selection list, and use a domain filter:

<field name="view" widget="ref-text"
  x-target="com.axelor.meta.db.MetaView"
  x-target-name="name"
  x-target-search="module"
  x-domain="self.model = :model AND self.type IN ('form', 'grid')" />

CodeEditor

The CodeEditor widget is a special widget for string data fields to use a code editor to input the source code text.

CodeEditor widget has two specials attributes:

  • x-code-syntax: syntax highlighting

  • x-code-theme: theme to style the editor. If not defined, use the default theme.

<field name="script" widget="code-editor" x-code-syntax="xml"/>
As part of the new v7 front-end built on top of React, x-code-theme is no more supported. It will be re-added in a future version.

HTML

The html editor widget is a special widget for string data fields to provide html text.

Html widget has a special attribute x-lite to use a compact and little version of the widget.

<field name="note" widget="html"/>

<!-- or use compact version of the widget -->
<field name="note" widget="html" x-lite="true"/>

Markdown

The Markdown widget is implemented with TOAST UI Editor and supports CommonMark and GFM specifications.

<field name="comment" widget="markdown"/>
Attribute Description

x-lite

Enable lite toolbar (defaults to false)

x-preview-style

Markdown editor’s preview style: tab (default), vertical

x-initial-edit-type

Initial editor type: markdown (default), wysiwyg

x-hide-mode-switch

Whether to hide edit typo switch tab bar (defaults to false)

InfoButton

This can be used on a button to dispay data bound to a record value (real or dummy). If the name of the button is the name of a field, it is bound to that field. Otherwise, use the x-field attribute to specify the bound field.

When using x-field, the button and the field are 2 distinct elements. Any attributes defined on that field will be used to format the value. Moreover, this allows to change the button attributes without impact on the bound field.

<panel>
  <button name="amountBtn" title="Amount" widget="info-button" x-field="amount" onClick="my-action"/>
  <field name="amount" hidden="true"/>
</panel>
