Flowfuse/Dashboard UI 2 - Send msg.payload with UI template

Hi all,

Beginner here.
Using the UI template node, i managed to build a succession of forms containing some fixed data from incoming msg.payload, a text field and a submit button.
I am trying now to send out a msg.payload containing that fixed data and the value entered in the text field.
I can send the fixed data using the @click on v-btn element. I can send the text-field value using the v-form submit. I can use both but it sends 2 separate msg.payload.
I have no clue on how to group both together and send a single msg.payload either upon button click or form submit.
Can one provide some guidance on how to achieve that ?

Thanks

Hi, welcome to the forum.

In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote ```)
