Model pop up hides below pdf document
We are using Pega 7.1.8 for our development. In one of the portal of our application, we are displaying a pdf document ( using a web service ) in one of the section. No issues for this.
As per our business requirement, when the user click on a link in the portal, a model dialog pop up ( Loan Search) should open in the portal , but it is opening below the pdf document.
How we can display the pop up above the pdf? Any help appreciated.
