Simplified example:
<v-list>
<v-list-item :to="bla/bla">
<v-menu>
<template v-slot:activator="{on}">
<v-btn v-on.prevent="on"/> // I tried .stop, .stop.prevent, self.prevent, prevent.stop
</template>
<div> bla </div>
<v-menu>
</v-list-item>
</v-list>
So as you can see child event v-on triggers v-menu and shows this div. But it also triggers parent :to event. Any ides?
