Where to set 'allow-forms' permission

[Anonymous]

Hi,

I am using an external library (lineup) in my custom visual, where I have a dialog with form submission. I am getting this error, when I submit the form.

Where can I set allow-forms to allow form submision? 

I setted it on developer console but it didnt work.

<iframe class="visual-sandbox" sandbox="allow-scripts allow-forms" name="visual-sandbox"></iframe>

Hi @Anonymous 

The error message warns that an Iframe is sand-boxed without a proper privileges

This is an example of a sand-boxed iFrame.

<iframe sandbox src="http://usercontent.example.net/getusercontent.cgi?id=12193"></iframe>

The sandbox attribute is not always automatically attached, because the sandbox attribute controls what is allowed.

When a pop-up is needed, the attribute will change

<iframe sandbox="allow-same-origin allow-scripts allow-popups allow-forms" src="http://usercontent.example.net/getusercontent.cgi?id=12193"></iframe>

The iFrame has to allow pop-ups, new windows, or scripts. Whatever you are trying (probably just navigation), the action is being blocked by a sandbox.
