Ask: single

To ask the user to make a choice out of a list of choices without branching in your flow

The 'Ask: Single' node lets you collect a single choice from users without cluttering your flow design. Unlike the 'Ask: Choice' node, which requires creating labeled branches for each possible answer directly in the flow, 'Ask: Single' allows you to manage all possible choices in the side panel.

Benefits:

• Cleaner flow design with fewer visual elements

• Easier to maintain – add or modify choices without rearranging flow connections

• Simplified navigation – all choices lead to the same next node

Trade-off:

• Cannot directly branch based on specific answers You require a separate 'Control flow: branch' node if you need conditional branching based on responses

The flow built with Ask: Choice nodes

The flow built with Ask: Single nodes

Like the 'Ask: Choice' node, each choice in 'Ask: Single' can have both a label and an intent. You can also configure tags to be set automatically based on the user's selection.

Each choice includes a value field, which determines what gets stored when assigning the answer to a variable. If you leave this field empty, the choice's label will be used as the default value.

This node will also set a user tag using the assign-to value. Don't forget to manually create this tag in the Tags page.

Dialog triggers

Special events can trigger another flow or set of nodes in your existing flow using the so called Dialog Triggers. See the chapter Dialog triggers for more details.
