Ai
<et2-ai> | Et2Ai
AI Assistant widget to process content of slotted elements
The widget provides an interface to an AI assistant that can process the content of its slotted element. It presents a dropdown menu with various prompts (e.g., summarize, fix grammar) and displays the result in a card for review before applying it back to the target widget.
Examples
None of the examples will work here in the docs as the AI agent cannot be accessed.
Single Target (Default)
By default, the widget processes the first element placed in its default slot.
<et2-ai>
<et2-textbox value="This is some text that needs to be more formal."></et2-textbox>
</et2-ai>
Multiple Elements (Nested Target)
If you want to process multiple fields together, or if your target is inside a container like Et2Box, the widget will attempt to extract values from the container using standard eTemplate2 methods.
<et2-ai>
<et2-vbox>
<et2-textbox label="Job" id="job_name" value="Do the thing with the thing"></et2-textbox>
<et2-textarea label="Details" id="body" value="Don't forget the meeting tomorrow at 10 AM."></et2-textarea>
</et2-box>
</et2-ai>
Custom Prompts
You can provide your own set of prompts. Prompts can define a target (where the result goes) and a mode (replace, append, or prepend).
<et2-ai id="custom-ai">
<et2-textarea id="my-target" value="Original content. "></et2-textarea>
</et2-ai>
<script>
const aiWidget = document.getElementById('custom-ai');
aiWidget.prompts = [
{
id: "aiassist.translate-de",
label: "Translate to German",
action: { target: "#my-target", mode: "replace" }
},
{
id: "custom.expand",
label: "Add more detail",
action: { target: "#my-target", mode: "append" }
}
];
</script>
Prompt IDs must be matched to a predefined prompt on the server.
Using Events to Interfere
You can listen for the et2-ai-apply event to modify the result before it is written to the target, or call preventDefault() to cancel the automatic application entirely.
<et2-ai id="event-demo">
<et2-textarea value="This text will be intercepted."></et2-textarea>
</et2-ai>
<script>
const eventAi = document.getElementById('event-demo');
eventAi.addEventListener('et2-ai-apply', (e) => {
// e.detail.result contains the AI output
// e.detail.target contains the element where it will be applied
if (confirm("Do you want to add a signature to the result?")) {
e.detail.result += "\n\nGenerated by AI Assistant";
}
// To stop the widget from automatically updating the target:
// e.preventDefault();
});
</script>

actions
|
Set Actions on the widget Each action is defined as an object: move: { type: “drop”, acceptedTypes: “mail”, icon: “move”, caption: “Move to” onExecute: javascript:mail_move” } This will turn the widget into a drop target for “mail” drag types. When “mail” drag types are dropped, the global function mail_move(egwAction action, egwActionObject sender) will be called. The ID of the dragged “mail” will be in sender.id, some information about the sender will be in sender.context. The etemplate2 widget involved can typically be found in action.parent.data.widget, so your handler can operate in the widget context easily. The location varies depending on your action though. It might be action.parent.parent.data.widget To customise how the actions are handled for a particular widget, override _link_actions(). It handles the more widget-specific parts. |
object
|
- | |
align
|
Used by Et2Box to determine alignment. Allowed values are left, right |
|
string
|
- |
class
|
CSS Class. This class is applied to the outside, on the web component itself. Due to how WebComponents work, this might not change anything inside the component. |

string

data

Set the dataset from a CSV |
string
|
- | |
deferredProperties
|
Any attribute that refers to row content cannot be resolved immediately, but some like booleans cannot stay a string because it’s a boolean attribute. We store them for later, and parse when they’re fully in their row. If you are creating a widget that can go in a nextmatch row, and it has boolean attributes that can change for each row, add those attributes into deferredProperties | - | - | |
disabled
|
Defines whether this widget is visibly disabled. The widget is still visible, but clearly cannot be interacted with. Widgets disabled in the template will not return a value to the application code, even if re-enabled via javascript before submitting. To allow a disabled widget to be re-enabled and return a value, disable via javascript in the app’s et2_ready() instead of an attribute in the template file. |

boolean
|
false

dom_id
|
Get the actual DOM ID, which has been prefixed to make sure it’s unique. |
string

hidden
|
The widget is not visible. As far as the user is concerned, the widget does not exist. Widgets hidden with an attribute in the template may not be created in the DOM, and will not return a value. Widgets can be hidden after creation, and they may return a value if hidden this way. |

boolean

- |
id
|
Get the ID of the widget |
string
|
- | |
label
|
The label of the widget This is usually displayed in some way. It’s also important for accessability. This is defined in the parent somewhere, and re-defining it causes labels to disappear |

Methods
| Name | Description | Arguments |
|---|---|---|
checkCreateNamespace()
|
Checks whether a namespace exists for this element in the content array. If yes, an own perspective of the content array is created. If not, the parent content manager is used. Constructor attributes are passed in case a child needs to make decisions | - |
clone()
|
Creates a copy of this widget. |
_parent: et2_widget
|
createElementFromNode()
|
Create a et2_widget from an XML node. First the type and attributes are read from the node. Then the readonly & modifications arrays are checked for changes specific to the loaded data. Then the appropriate constructor is called. After the constructor returns, the widget has a chance to further initialize itself from the XML node when the widget’s loadFromXML() method is called with the node. |
_node: , _name:
|
getArrayMgr()
|
Returns the array manager object for the given part |
managed_array_type: string
|
getArrayMgrs()
|
Returns an associative array containing the top-most array managers. |
_mgrs: object
|
getChildren()
|
Get child widgets Use |
- |
getInstanceManager()
|
Returns the instance manager | - |
getPath()
|
Returns the path into the data array. By default, array manager takes care of this, but some extensions need to override this | - |

parseXMLAttrs()
|
The parseXMLAttrs function takes an XML DOM attributes object and adds the given attributes to the _target associative array. This function also parses the legacyOptions. N.B. This is only used for legacy widgets. WebComponents use transformAttributes() and do their own handling of attributes. |
_attrsObj: , _target: object, _proto: et2_widget
|
set_label()

|
setArrayMgr()
|
Sets the array manager for the given part |
