Creating a stop in snippet "string"

I got this snippet and trying to create the next stop inside of the options. So first I select the type of, lets say I select v-if="NEXT-SHOULD-BE-HERE". How can I do that?

"Select template": {
    "prefix": ["templatetype"],
    "body": [
        "<template ${1|#:,v-if=\"\",v-for=\"\"|}>",
        "  ${2}",
        "</template>"
    ],
    "description": "Create a template and select type"
}
