Answer 1

The following argument(s) in $emit() are the arguments in your emitted function.
$emit('select-menu-item', $event, 1, 2, 3, 4, "cupcakes")
and in your component method.
selectMenuItem: function(evt, num1, num2, num3, num4, food){
}
And in your actual component markup, you don't need to add arguments, just write the reference to the method without parenthesis.
<search-component v-bind="searchProps" #select-menu-item="selectMenuItem">
SAMPLE
window.onload = function(){
const component = function() {
return {
template: `
<div>
<button #click="$emit('click-me', 'foobar')">
Click Me
</button>
</div>
`,
props: ["data"]
}
}
new Vue({
el: container,
data: {},
components: { "my-component": component(), },
methods: {
clickMe: function(str){
console.log(str);
}
}
});
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="container">
<my-component :data=$data #click-me="clickMe"></my-component>
</div>

just adding more answer from #Albana Clara.
You can merge your parameter along with the event passed.
EXAMPLE:
<search-component v-bind="searchProps" #select-menu-item="selectMenuItem('test', ...arguments)">
selectMenuItem: function(a, b) {
console.log(a + " " + b);
// test foobar
}

If anyone searching how emits work in Vue3 with Composition API:
In the child component:
<script setup>
const emit = defineEmits(["updateItem", "updateCount"])
function itemizedLot() {
emit("updateItem", param1, param2)
}
function countedLot() {
emit("updateCount", param3, param4)
}
</script>
<template>
<button #click="itemizedLot"> Btn1 </button>
<button #click="countedLot"> Btn2 </button>
</template>
In the parent component:
<script setup>
// access the emitted methods and their parameters
function updateMenuItem(param1, param2) {
...
}
function updateMenuCount(param3, param4) {
...
}
</script>
<template>
<MyButton #update-item="updateMenuItem" #update-count="updateMenuCount"/>
</template>
