What is a Vuetify v-menu component 'save' method?-CodePudding

There is an example in Vutetify documentation (https://vuetifyjs.com/en/components/date-pickers/#dialog-and-menu). That example has next template code snippet:

...
      <v-menu
        ref="menu"
        v-model="menu"
        :close-on-content-click="false"
        :return-value.sync="date"
        transition="scale-transition"
        offset-y
        min-width="auto"
      >
        ...
        <v-date-picker
          v-model="date"
          no-title
          scrollable
        >
          ...
          <v-btn
            text
            color="primary"
            @click="$refs.menu.save(date)"
          >
            OK
          </v-btn>
        </v-date-picker>
      </v-menu>

It looks like that when a button click ( @click="$refs.menu.save(date)" ) occurs, some 'save' method of the v-menu component is called. But where is it possible to see information about Vuetify component methods and particularly about that menu save method?

CodePudding user response：

The save() method is provided by the Returnable mixin, which allows control over the value returned by the return-value property.
