Dashboard 2 : Radiogroup based on the template

Hi all.

I am all time studying dashboard 2, to xchange my old DB1. But always I took any special code, what blocks me to continuing.
I need dialog window in template 2 which can send a value after click Exec command to output. But this "new" method and all related commands in script are still unknown for me. Also the radio function - switching dots between selections - are not running.
Please, help, if you have any knowledge :

Thanks a lot for your time.

For the dialog, you should be able to do that using a Group of type Dialog. This gives you a modal popup that you can put any widgets you like into. Then use a ui-control to show/hide the dialog.

For the radio buttons does a radio group widget do what you want?

@Colin yes, show/hide is OK. But I do not know, how the result (value) of the radio send to payload output.
And also, I do not have any minds, how the "template button" style to line to row. Because, this is out of row - half row bellow standard buttons.

I don't understand. Do you mean that the radio group widget (Radio Group ui-radio-group | Node-RED Dashboard 2.0) is not sending any output?

Why are you using template nodes not the built in nodes?

Because, I need radio group as a dialog popup window. And I am newbie in DB2 and do know about more new things opposite DB1.
I have tried following, and is looking good :

<template>
  <div class="pa-4 text-center">
    <v-dialog
      width="auto"
      scrollable
    >
      <template v-slot:activator="{ props: activatorProps }">
        <v-btn
          color="brown"
          prepend-icon="mdi-timer-play-outline"
          text="Get select command"
          v-bind="activatorProps"
        ></v-btn>
      </template>

      <template v-slot:default="{ isActive }">
        <v-card
          title="Select remote command :"
        >
          <v-divider class="mt-3"></v-divider>

          <v-card-text class="px-4" style="height: 250px;">
            <v-radio-group
              v-model="SelectedVal"
            >
              <v-radio
                label="NOT SEL"
                value="0"
              ></v-radio>

              <v-radio
                label="Details"
                value="1"
              ></v-radio>

              <v-radio
                label="Errors reset"
                value="2"
              ></v-radio>

              <v-radio
                label="Output disconn."
                value="3"
              ></v-radio>

              <v-radio
                label="Battery test"
                value="4"
              ></v-radio>

              <v-radio
                label="Ext.relay On"
                value="5"
              ></v-radio>

            </v-radio-group>
          </v-card-text>

          <v-divider></v-divider>

          <v-card-actions>
            <v-btn
              text="Close"
              @click="isActive.value = false"
            ></v-btn>

            <v-spacer></v-spacer>

            <v-btn
              color="surface-variant"
              text="Exec command"
              variant="flat"
              @click="send({payload: SelectedVal}), isActive.value = false"
              
            ></v-btn>
          </v-card-actions>
        </v-card>
      </template>
    </v-dialog>
  </div>
</template>

<script>
    export default {
  data() {
    return {
      SelectedVal:null
    }
  }
  }
</script>

But, at the end I must styling button to line, because, actually is out of row (brown one) :

Use a radio group widget (not a template) in a ui group configured to be of type Dialog, and use a ui-control node to show/hide the dialog group. No need for a template.
