This tag defines a set (at least one) sample text of response which can be sent by the user in this particular state.
In terms of some messengers like Facebook Messenger, Slack, Kik or Telegram it is a set of buttons which will be rendered under the bot\'s response bubble.
- a set of items
With this feature you can provide the user with some set of sample responses he can use on the next step of dialog. For example, if your bot responses with “What is your preferred color?”, it can also provides samples of answers like “Green”, “Blue” and etc.
These samples may be rendered by messenger as a buttons. User can click on one of them instead of typing the response.
Please note that not every messenger supports buttons. In this case this tag will be ignored.
The definition of this tag is very similar to the output tag:
<input pattern="(hi|hello) *"> <output value="Hi! What is your favorite color?"/> <context> <input pattern="* $Color"/> <sample> <item>Green</item> <item>Blue</item> <item>Red</item> </sample> </context> </input>
Instead of selecting randomly only one of inner items, Zenbot will create a list of samples and return it in the response. Thus in this particular case the messenger will respond with bubble “Hi! What is your favorite color?” with three buttons under it - “Green”, “Blue” and “Red”. Once the user clicks one of the buttons, your bot will receive a request with text of this button - as if the user has typed it manually.
Similar to output tag Zenbot will replace all placeholders in the sample's context with particular value of the appropriate variable.
You can define multiple sample tags one by one:
<sample lang="ru"> <item value="Белый"/> <item value="Синий"/> <item value="Красный"/> </sample> <sample> <item value="White"/> <item value="Blue"/> <item value="Red"/> </sample>
Zenbot will select the very first sample tag shich satisfies all of defined conditiona (if any) and ignore all others sample tags. In this particular case Zenbot will generate samples set from the first one only if user speaks Russian. Otherwise the second sample tag will generate such set of buttons.
You can use the value attribute to define a sample'a content instead of using of enclosing tags:
<sample> <item value="Button 1"/> <item value="Button 2"/> </sample>
Moreover, if you have to define only one sample, you can use value attribute right in the sample tag:
<sample value="Cancel this reminder"/>
A set of sample tag attributes is the same as for output tag.
