Add title to the iframe(google map)

What do you mean Title? You trying to add HTML before the IFrame? If so, should be able to add it in the HTML Before of the webpart.

If you want to modify the content inside an IFrame,you can't most likely., but you would have to do it with javascript.

Hi, Thanks for your reply. By saying title,I mean to say,adding title attribute in the iframe tag.

Thanks.

That IFrame is created by the Google Maps API, so there is no way to set it outside of JavaScript.

You will have to do something like this:

google.maps.event.addListenerOnce(map, 'idle', () => {
  document.getElementsByTagName('iframe')[0].title = "Google Maps";
})

You can add this to the GoogleMaps.js file in the Maps/Basic/BasicGoogleMaps_files folder.
