Create own decorator in my-plugin

Hello!

How can I change standart or add new decorator to my plugin???

I have to change “main” menu in Admin console. Hide “Server” menu for example.

Thanks

here is my solution:

<script type=“text/javascript”>
window.onload = function() {
//hide main menu
var menu = document.getElementById(“jive-nav”);
if (menu) {
menu.style.display =“none”;
}
}
</script>
