I have a chat widget configured like this:

let chat = $(target).kendoChat({
			messages: {
        placeholder: ResourceManager.GetInstance().getResource("SR_TYPE_A_MESSAGE")
      },
      user: user, 
      post: async (m: kendo.ui.ChatPostEvent) => await this.post(m),
    }).data("kendoChat");

If the post handler tries to await a call to a web  service (to do some translation/tag substitution) then the message is posted to the chat and the results of the web call are ignored.

The current chat widget renders the user-input as an INPUT control, which means it cannot support multi-line support.

Wish for the option of rendering a TEXTAREA control instead of an INPUT for the chat widget:

let chat = $(target).kendoChat({
  messages: {
        placeholder: ResourceManager.GetInstance().getResource("SR_TYPE_A_MESSAGE"),
        textarea: true
    },
      user: user, 
      post: async (m: kendo.ui.ChatPostEvent) => await this.post(m),
    }).data("kendoChat");

With version 2024.1.319, the sendMessage of chat is called twice whereas the bug doesn't exist in version 2022.3.913.

Is there a solution?

The function kendo.chat.registerTemplate as mentioned here: https://docs.telerik.com/kendo-ui/controls/conversational-ui/chat/chat-items#custom-templates is missing in API Reference and the Typescript Definitions.

It would also be nice to have it documented in functions that are using the templates, for example the "message.type" parameter in https://docs.telerik.com/kendo-ui/api/javascript/ui/chat/methods/rendermessage
