Hello friends, today we will discuss Use IFrame in LWC component in Salesforce. We use an iframe to load other website pages. Like if you want to show third-party page eg. then you just need to put this URL link in iframe src. We can give height and width in the iframe. We also use event listeners like onload for the call LWC js method.

  2. We also use iframe for generating pdf.
