I have a User/Team owned Custom entity. In the form of that entity I have added one IFrame control in the form. By default I check the option "Restrict cross-frame scripting, where supported" while adding. Now I have to uncheck this option and I am unable to uncheck that option.
In that IFRame control I am showing SharePoint List or grid. But it is not able to use that grid and giving error as "Script execution is blocked because the documents IFrame is sandboxed and the 'allow-scripts' permission is not set." Due to this error message I need to uncheck "Restrict cross-frame scripting, where supported" option in IFRAME control.
Can anyone please help me out on this.
