Single Select

Single Select — CometChat documentation.

Overview

The CometChatSingleSelect component is a customizable Single Select component that allows you to choose one option from a list of box-structured options. It extends from the LitElement’s base class.

While this design allows an intuitive interaction similar to radio buttons, its unique box-style presentation provides a distinctive user experience. If only two options are provided, they are displayed side-by-side. For more than two options, they are displayed vertically.
