Frequently Asked Questions
Can I set the IFrame to load synchronously or asynchronously?
You can choose between synchronously or asynchronously IFrame loading. In the setting Load Async, if you want the IFrame to load after the page has fully loaded, select the Yes option.
If you want the IFrame to start loading in parallel as the page loads, choose the No option.
To disable the scrollbars on your IFrame can be done by selecting the option No in the setting Scrollbars.
Please note that you can also set them to be enabled by default by selecting the option Yes and also be in auto mode by
selecting the options Auto.
Can I add custom HTML attributes to the IFrame?
You can set any custom html attributes you desire via the setting HTML Attributes. Simply add the attributes you desire and they
will be included with the IFrame on the front-end.
Notes
It should be noted that a website can be configured so that they are not allowed to be viewed through an iframe from a different website. In this case the iframe will load a blank page.
It should also be noted that some popular browsers disallow the loading of iframes which contain non-HTTPS content on webpages which are under HTTPS. This policy is called Mixed Content Blocking and has been the norm since at least 2013.
