Dropdown in Lightning Web Component (LWC)

How to create and use the dropdown in the Lightning Web Component.


Lightning-Combobox is an alternative of Lightning: Select Aura Component.

First, let us create a custom dropdown.

    <label for="FieldSelect" class="slds-form-element__label slds-no-flex">
        <abbr title="required" class="slds-required">*</abbr>//in case you want to mark required
        Select Filter Condition
    <select class="slds-select" name = "optionSelect" onchange={changeHandler} >
        <option value="OPTION A">OPTION A</option>
        <option value="OPTION B">OPTION B</option>
import { LightningElement, api,track } from 'lwc';
import getFields from '@salesforce/apex/wk_FilterComponent.getFields';
export default class FilterComponent extends LightningElement {
    @track selectedOption;
    changeHandler(event) {
    const field = event.target.name;
    if (field === 'optionSelect') {
        this.selectedOption = event.target.value;
            alert("you have selected : "this.selectedOption);

Alternatively, you can also use standard lightning web component i.e., Lightning Web Component Combobox.

               placeholder="Select Progress"
               onchange={handleChange} >
   <p>Selected value is: {value}</p>
import { LightningElement, track } from 'lwc';

export default class ComboboxBasic extends LightningElement {
@track value = 'inProgress';

get options() {
    return [
             { label: 'New', value: 'new' },
             { label: 'In Progress', value: 'inProgress' },
             { label: 'Finished', value: 'finished' },

handleChange(event) {
        this.value = event.detail.value;
