Modal/Popup in Lightning Web Component (LWC)

In this post we will talk about how to create modal/Popup in Lightning web Component (LWC). Currently "lightning:overlayLib" is not available in LWC, the only way to show modals and popups is through styling and making a custom html modal. Modals/Popup Box are used to display content in a layer above the app. Mostly used to creation or editing of a record, as well as various types of messaging and wizards.

If you want to know how to create Modal in Lightning aura component, please refer to this post.

Modal / Popup Example Lightning Web component(LWC)

You can take a help from SLDS for creating the modals. Code has following three main part

Create Lightning web component in your sandbox or developer org.

    <lightning-button variant="success" label="Open popup"
                        title="Open popup" onclick={showModalBox}>

   <!-- modal start -->      
   <template if:true={isShowModal}>

                I Used SLDS for this code
                Here is link

    <section role="dialog" tabindex="-1" aria-labelledby="modal-heading-01" aria-modal="true" aria-describedby="modal-content-id-1" class="slds-modal slds-fade-in-open">
       <div class="slds-modal__container">
        <!-- modal header start -->
          <header class="slds-modal__header">
             <button class="slds-button slds-button_icon slds-modal__close slds-button_icon-inverse" title="Close" onclick={hideModalBox}>
                <lightning-icon icon-name="utility:close"
                   size="small" ></lightning-icon>
                <span class="slds-assistive-text">Close</span>
             <h2 id="modal-heading-01" class="slds-text-heading_medium slds-hyphenate">Welcome in Apex Hours</h2>
          <!-- modal body start -->
          <div class="slds-modal__content slds-p-around_medium" id="modal-content-id-1">
                <p>Modal/Popup in Lightning Web Component (LWC) Demo</p>

          <!-- modal footer start-->
          <footer class="slds-modal__footer">
             <button class="slds-button slds-button_neutral" onclick={hideModalBox}>Cancel</button>
    <div class="slds-backdrop slds-backdrop_open"></div>
 <!-- modal end -->

  • Enable and disable the modal with template if:true
  • Use section role='dialog'

import { LightningElement,track } from 'lwc';

export default class ModalDemoInLWC extends LightningElement {
    @track isShowModal = false;

    showModalBox() {  
        this.isShowModal = true;

    hideModalBox() {  
        this.isShowModal = false;

<?xml version="1.0" encoding="UTF-8"?>
<LightningComponentBundle xmlns="">
