Portal having IE Compatibility issue in edge

Hi,

We have a requirement to use edge and we have AJax standard headerless framework page which have doc mode to edge. When assign to a user, by default document mode is set this to IE=edge.

We have Compatibility issue with IE, all the left navigation, header applications the alignment changed and not working properly but working in IE=5

In JSP of custom header application, I have set the meta data <meta http-equiv="X-UA-Compatible" content="IE=edge:/>, but still it is not working.

Not sure which one is the parent file where I can set the meta tags?

Is there any other way I can set IE=edge for document mode?

Could you please help me with this issue.

Thanks & Regards,

Prasad
