JET components that allow child content support slots. Please see the slots section of the JET component overview doc for more information on allowed slot content and slot types.
-
contextMenu
-
The contextMenu slot is set on the
oj-menu
within this element. This is used to designate the JET Menu that this component should launch as a context menu on right-click, Shift-F10, Press & Hold, or component-specific gesture. If specified, the browser's native context menu will be replaced by the JET Menu specified in this slot.The application can register a listener for the Menu's ojBeforeOpen event. The listener can cancel the launch via event.preventDefault(), or it can customize the menu contents by editing the menu DOM directly, and then calling refresh() on the Menu.
To help determine whether it's appropriate to cancel the launch or customize the menu, the ojBeforeOpen listener can use component API's to determine which table cell, chart item, etc., is the target of the context menu. See the JSDoc of the individual components for details.
Keep in mind that any such logic must work whether the context menu was launched via right-click, Shift-F10, Press & Hold, or component-specific touch gesture.
- Deprecated:
-
Since Description 13.0.0
This web component no longer supports launching a context menu.
Attributes
-
(nullable) described-by :string
-
The oj-label sets the described-by attribute programmatically on the form component. This attribute is not meant to be set by an application developer directly. The described-by is copied to the aria-describedby attribute on the component's inner dom element, and it is needed for accessibility.

- when a required component is initialized as disabled
value="{{currentValue}}" required disabled
, deferred validation is skipped. - when a disabled component is enabled,
- if component is invalid and showing messages then all component messages are cleared,
and full validation run using the display value.
- if there are validation errors, they are shown.
- if no errors result from the validation, the

property is updated. Page authors can listen to thevalueChanged
event to clear custom errors.
- if component is valid and has no errors then deferred validation is run.
- if there is a deferred validation error, then the valid property is updated.
- if component is invalid and deferred errors then component messages are cleared and
deferred validation re-run.
- if there is a deferred validation error, then the valid property is updated.
- if component is invalid and showing messages then all component messages are cleared,

display-options :Object
-
Display options for auxiliary content that determines whether or not it should be displayed.
In the Redwood theme, the sub-properties of the display-options configure whether or not the types of information is shown. The values of these sub-properties are either 'display' or 'none'.
When display-options changes due to programmatic intervention, the component updates its display to reflect the updated choices. For example, if you don't want to show the converter hint, set the display-options.converter-hint to 'none'.
A side note: help.instruction and message detail text can include formatted HTML text, whereas hints and message summary text cannot. If you use formatted text, it should be accessible and make sense to the user if formatting wasn't there. The allowed html tags are: span, b, i, em, br, hr, li, ol, ul, p, small, pre. To format the help.instruction, you could do this:
<html>Enter <b>at least</b> 6 characters</html>

help.instruction :string
-
A type of user assistance text. User assistance text is used to provide guidance to help the user understand what data to enter or select.
In the Redwood theme for clarity only one user assistance text shows to the user. The precedence rules are:
- help.instruction shows;
- if no help.instruction, then validator hint shows;
- if no help.instruction or validator hint, then help-hints.definition shows;
- if no help.instruction, validator hint, or help-hints.definition, then converter hint shows.
- help-hints.source always shows along side the above.
In the Redwood theme, by default all user assistance text shows inline. For input components, it shows when the field takes focus. In other components it shows all the time. See the user-assistance-density property for other ways the user assistance text can render.
How is help.instruction better than the html 'title' attribute? The html 'title' attribute only shows up as a tooltip on mouse over, not on keyboard and not in a mobile device. So the html 'title' would only be for text that is not important enough to show all users, or for text that you show the users in another way as well, like in the label. Also you cannot theme the native browser's title window like you can the JET notewindow, so low vision users may have a hard time seeing the 'title' window. For these reasons, the JET EditableValue components do not use the HTML's 'title' attribute and instead use the help.instruction attribute.
To include formatted text in the help.instruction, format the string using html tags. The allowed html tags are: span, b, i, em, br, hr, li, ol, ul, p, small, pre. For example the help.instruction might look like:
If you use formatted text, it should be accessible and make sense to the user if formatting wasn't there.<oj-some-element help.instruction="<html>Enter <b>at least</b> 6 characters</html>"></oj-some-element>

label-edge :('inside'|'none'|'provided')
-
Specifies how the label of the component is created when the
label-hint
attribute is set on the component.The default value varies by theme, and it works well for the theme in most cases. If the component is in an oj-form-layout, the label-edge attribute could come from the oj-form-layout's label-edge attribute. The oj-form-layout component uses the MetadataTypes.PropertyBinding
provide
property to provide and uses the MetadataTypes.ProvidePropertytransform
property to transform itslabel-edge
attribute to any descendent components that are configured to consume it. For example, if the oj-form-layout's label-edge attribute is set to "top" or "start", and a descendent form component does not have its label-edge attribute set, the form component's label-edge will be the transformed value "provided".- Since:
- 8.0.0
Supported Values:
Value Description inside
The component creates the label using the label-hint
attribute.For text input components (such as oj-input-text), the label floats over the input element but moves up on focus or when the component has a value.
For non-text input components (such as oj-checkboxset), the label is created at the top of the component and doesn't move.
none
The component will not have a label, regardless of whether it's in an oj-form-layout or not. If the component has a
label-hint
attribute but no labelled-by, aria-label, or aria-labelledby attribute, the label-hint value will be used as the aria-label.Note that if the component already has an external label, "none" should not be specified and "provided" should be used instead. Otherwise it may end up with conflicting label information.
provided
Label is provided by the parent if the parent is an oj-form-layout. oj-form-layout provides the label using the label-hint from the form control and the label-edge from oj-form-layout.
If there is no oj-form-layout, use an oj-label.

label-hint :string
-
Represents a hint for rendering a label on the component.
This is used in combination with the label-edge attribute to control how the label should be rendered.
When label-edge is "provided", it gives a hint to oj-form-layout parent element to create an oj-label element for the component. When the
label-hint
attribute changes, oj-form-layout element refreshes to display the updated label information.When label-edge is "inside", it gives a hint to the component itself to render a label.
When label-edge is "none", and if the component has no labelled-by, aria-label, or aria-labelledby attribute, the label-hint value will be used as the aria-label.

The application developer should use the 'for'/'id api to link the oj-label with the form component; the 'for' on the oj-label to point to the 'id' on the input form component. This is the most performant way for the oj-label to find its form component.

messages-custom :Array<oj.Message>
-
List of messages an app would add to the component when it has business/custom validation errors that it wants the component to show. This allows the app to perform further validation before sending data to the server. When this option is set the message shows to the user right away. To clear the custom message, set
messagesCustom
back to an empty array.
Each message in the array is an object that duck types oj.Message. See Message for details. message detail text can include formatted HTML text, whereas hints and message summary text cannot. If you use formatted text, it should be accessible and make sense to the user if formatting wasn't there. The allowed html tags are: span, b, i, em, br, hr, li, ol, ul, p, small, pre. To format the message detail, you could do this:
<html>Enter <b>at least</b> 6 characters</html>
See the Validation and Messages section for details on when the component clears
messagesCustom
; for example, when full validation is run.In the Redwood theme, the Message summary is not displayed to the user, so make sure to have a Message detail set in your Message object.

user-assistance-density :('reflow'|'efficient'|'compact')
-
Note: This attribute is not supported in the following themes:
Alta
-
Specifies the density of the form component's user assistance presentation. It can be shown inline with reserved rows to prevent reflow if a user assistance text shows up, inline without reserved rows that would reflow if a user assistance text shows up, or it can be shown compactly in a popup instead.
The default value is 'reflow' when the form component is not a descendent of an oj-form-layout component. When the form component is a descendent of an oj-form-layout, the default value comes from the oj-form-layout's
user-assistance-density
attribute value.The oj-form-layout component uses the MetadataTypes.PropertyBinding
provide
property to provide itsuser-assistance-density
attribute value to be consumed by descendent components. The form components are configured to consume theuser-assistance-density
property if an ancestor provides it and it is not explicitly set on the form component. Example, oj-form-layout defaults user-assistance-density='efficient', so all its form components descendents will have user-assistance-density='efficient' by default.- Default Value:
"reflow"

-
The current valid state of the component. It is evaluated on initial render. It is re-evaluated
- after each validator (validators or async-validators) is run (full or deferred)
- when messagesCustom is updated, since messagesCustom can be added by the app developer any time.
- when showMessages() is called. Since showMessages() moves the hidden messages into messages shown, if the valid state was "invalidHidden" then it would become "invalidShown".
- when the required property has changed. If a component is empty and has required set, the valid state may be "invalidHidden" (if no invalid messages are being shown as well). If required property is removed, the valid state would change to "valid".
Note: New valid states may be added to the list of valid values in future releases. Any new values will start with "invalid" if it is an invalid state, "pending" if it is pending state, and "valid" if it is a valid state.
