I have used a sample archetype to create pages in AEM 6.4. However, I am not able to use the layout feature as it is not appearing in dropdown. What could be its reason ? I have tried looking for it on the web only to fail. Please Help !
There could be a chance that the template was not created properly. Could you please recheck ? Also are you using static template or editable template ? Can you give a screen shot of the options you are getting ?
