Static Choice user input control
Use the Static Choice user input control in a Virtual Agent topic to list predefined choices available to the user. You can select only one item from a choice list.
Choice display
The choice list contains up to 10 items per page. When more than 10 items exist in an NLU conversation, you have the option to show the additional items and also filter the search results. The choice list prompt contains a search icon

The Static Choice control provides the option to add a header card that displays above the choice list. Header cards are supported in web and mobile channels.
The header card can contain a large or small image or a YouTube video card, along with descriptive text. The choice list contains up to five items by default, but the search feature is suppressed. If there are more than five items, users can choose to show the additional items.
To control the number of items displayed below a header card, add the com.glide.cs.web_header_picker_page_limit system property. Use the Value to specify the number of items displayed in the choice list. For details about creating a system property, see Add a system property.
Static Choice user input control properties for LLM topic discovery
| Property | Description |
|---|---|
| Name | Name that identifies this node in the topic flow. |
| Variable name | Name of the variable that stores the user response to this prompt. The variable name is automatically created from the Node name property. |
| Allow automatic slot-filling | Toggle to allow this node’s value to be automatically set by other nodes, as well as during topic discovery. When this toggle is activated, the Detail description field changes from dynamic Data Pill Picker and script options to a static text field. |
| Detail description | Description of the information that you need from users. If the Allow automatic slot filling toggle is deactivated, you can create a dynamic detail description by selecting the Data Pill Picker icon Image omitted: variable-reference-picker.png to define conditions, or select the Open Editor icon [Omitted image "icon-script.png"] Alt text: to enter a script. If the <strong>Allow automatic slot filling</strong> toggle is activated, you can only enter a static description.</p> Image omitted: LLM-input-discoverable-toggle.png ChoicesWhen the Allow automatic slot-filling toggle is inactive, the detail description includes Data Pill Picker and script dynamic options. When the toggle is active, the Detail description field becomes static.</p></td></tr><tr><td class="sub-head" colspan="2"> |
| Display name | For each choice, the text that appears to the user for that choice. Use short phrases in your choice lists. - Slack has a limit of 30 characters for choice list labels. - Workplace has a limit of 20 characters for choice list labels. |
| Value | For each choice, the string that is stored in the variable when the corresponding choice is selected. |
| Advanced | |
| Header Card | Toggle to open a field to add cards which may include images or YouTube videos. For more information, see Insert a header card in a Static Choice or Dynamic Choice control |
| Enforce user prompt | Toggle to open a field for a custom message shown to the user instead of the message generated by the large language model \(LLM\). You can create custom messages in plain language, input a script, or define conditions with the data pill picker. |
| Validation | Add a script to validate the user input. For example, check if the user entered a valid email address. |
| Additional instructions for LLM | Further instructions to the LLM, such as adding data formats, restrictions, or default values for user responses. You can create additional instructions in plain language, input a script, or define conditions with the data pill picker. |
| Hide or skip this node | |
| Conditionally use this node if | No-code condition statement or low-code script that specifies a condition for presenting this node in the conversation. The condition must evaluate to true. |
| Allow user to skip this node if | No-code condition statement or low-code script that specifies a condition for letting users skip this node in the conversation. The condition must evaluate to true. You can set this field using either the condition builder or a script. If users enter a value such as `skip this step` when the conditions do not allow skipping, they receive a message saying the node cannot be skipped and are re-prompted to provide an answer. |

Static Choice user input control properties for NLU topic discovery
| Property | Description |
|---|---|
| Node name | Name that identifies this node in the topic flow. |
| Detail description | The one piece of information needed from the user. For example, `Ask the user which service catalog item they need.` |
| Variable name | Name of the variable that stores the user response to this prompt. The variable name is automatically created from the Node name property. |
| Prompt | Prompt or question for the user. The prompt can be either a text string or a script that returns text. This value is used only when the default value is not specified. For example: You can create rich text to alter the styling of the prompt:
|
| NLU entity | Option to associate an NLU entity with the node. If an NLU entity is associated with the input variable for this node, Virtual Agent can slot-fill the specified value based on the user's utterance. Select an entity from the list of entities associated with the topic intent. When you specify an entity for the node, the Do not ask users to confirm recognized entity toggle switch is displayed. When enabled, users are not prompted to confirm the extracted entity. This field is available only when NLU discovery is enabled on the instance. |
| Choices | |
| Display name | For each choice, the text that appears to the user for that choice. Use short phrases in your choice lists. - Slack has a limit of 30 characters for choice list labels. - Workplace has a limit of 20 characters for choice list labels. |

| Default value | |
| Default Value | Predefined value for the user response to the question or prompt. The response defined in the Default value confirmation field asks the user to confirm the default value. If the user responds with no, the value becomes null. The default value can be either a text string or a script that returns text. For example, if you're using dot-walking, the default value might be: Script Variables > Last username. Or if you're using a script, the default value might be: {{vaScripts.lastUsername}}. |
| Confirmation messages | |
| Input completion confirmation | Bot response shown to the user when the node interaction is complete. The message can be either a text string or a script that returns text. For example, if you're using dot-walking: `Thanks, (Input Variables > Username)!` Or if you're using a script, the acknowledgement might be: `Thanks, {{vaInputs.username}}!` |
| Default value confirmation | Message that asks the user to verify that the value in the Default value field is correct. This message is used instead of a value in the Prompt field. It can contain either a text string or a script that returns text. For example, if you're using dot-walking: Are you (Input Variables > Username)? Or if you're using a script, the confirmation message might be: Are you {{vaScripts.lastUsername}}?. |

| This section is available only when NLU discovery is enabled on the instance. | |
| Turn on to let users change the subject | Option to enable NLU prediction for this node. If enabled, users can enter text to answer questions, regardless of the type of input control being used. Virtual Agent uses this utterance to match another existing intent, letting the user switch topics. |
