We have a custom application built for end users to request a new site for our on premise SharePoint environment. Now we are migrating to Office 365 and it would be a hybrid environment. In this context, we would like to use our custom application link on the Create Site button. We were able to update the link, now when we click on this button, the custom application is being opened in a modal window as shown in the screen shot below. My question - is there a way to customize this modal window not to show scroll bars? Your input is appreciated.
Our custom application when browsed without the link.
