I want to use action sheet for a menu and I used same code provided on docs for Action Sgeet but I a different plain viewm, and I can not see any css style used however I get a simple view, why this happens and how can I get same visuality ?
If you want an ios element in a auto designed app you will have to create the css on your own. F7 is designed to have a native feeling on all of the elements for each operating system.
You have to set the icons on your own as they are not part of the F7 base. You can use the ios-only and md-only classes to show only the icons you need.
