This problem affects Internet Explorer 11 or earlier (this problem doesn’t affect other browsers such as Edge, Chrome, and Firefox). Core Content Suite applications seem to work fine; however, custom applications that have their own html headers such as display views and custom views may not work as expected.
To check whether your copy of Internet Explorer is running in “Edge” mode, log-in to your Content Suite platform, right-click the page and select “Inspect” and then check the mode in the far right of the console; see the screenshot below.
If your IE version is the same as the selected mode (in the screenshot it’s set to 11) then IE is running in Edge mode then emulation mode is not the solution. If your IE version is greater than the selected mode, however, then you’re not running in Edge mode. In this case, force IE to operate in Edge mode may be the solution to your problem.
Therefore, best practice is to force IE to operate in Edge mode. To do so, add the following to your HTML source (such as a form’s customview)
<meta http-equiv=”X-UA-Compatible” content=”IE=Edge” />
This tag forces IE to use Edge mode.
