Is there a way to activate the <select> or <b-form-select> dropdown menu when hovering over it, without relying on JQuery or any third-party plugin except for Vue.js?
Is there a way to activate the <select> or <b-form-select> dropdown menu when hovering over it, without relying on JQuery or any third-party plugin except for Vue.js?
Based on my understanding, it seems like you are looking to toggle the visibility of <b-form-select> using the mouseover and mouseleave events. If this is correct, I have a few recommendations :
mouseover and mouseleave events. You can directly employ the mouse events by adding the native attribute to the element itself. However, keep in mind that once the dropdown is hidden, there may not be a straightforward way to make it reappear on mouseover.v-show directive to show/hide the dropdown. This allows for easy manipulation of the visibility based on the mouse events.View the Demo :
new Vue({
el: '#app',
data() {
return {
selected: null,
isVisible: true,
options: [
{ value: null, text: 'Please select an option' },
{ value: 'a', text: 'This is First option' },
{ value: 'b', text: 'Selected Option' },
{ value: { C: '3PO' }, text: 'This is an option with object value' },
{ value: 'd', text: 'This one is disabled', disabled: true }
]
}
},
methods: {
onOver() {
this.isVisible = true;
},
onLeave() {
this.isVisible = false;
}
}
}).wrapper-div {
height: 20px;
}<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

<div id="app">
<div class="wrapper-div" @mouseover="onOver" @mouseleave="onLeave">
<b-form-select
v-model="selected"
:options="options"
v-show="isVisible">
</b-form-select>
</div>
</div>When using this solution, the outcome is akin to triggering the select option as if it had been clicked on (though not exactly the same...)
<template>
<select ref="mySelect" @mouseenter="hover(true)" @mouseleave="hover(false)" :size="size">
<option value="1">option 1</option>
<option value="2">option 2</option>
<option value="3">option 3</option>
</select>
</template>
<script>
import {ref} from 'vue';
export default {
name: "Test",
setup(){
const mySelect = ref();
const size = ref('0');
return {mySelect, size}
},
methods: {
hover(val) {
this.size = val ? this.mySelect.length.toFixed(0) : '0';
}
}
}
