Is there any possibilities to add subtitle in multi select custom template?
As mentioned in the document https://developer.kore.ai/docs/bots/sdks/message-templates/ under custom templates, you can customize these given custom templates as per your requirement.
The dropdown template and the multi-select templates are given as sample to build your own custom templates.
You can find the code for the multi-select template in customTemplate.js and customTemplate.css.
To add another field as subTitle, you need to make necessary changes in the code in customTemplate.js.
Let us know if you need any further information.
