Is there some way to create a widget or placeholder for some content that should be only shown if i use some special tag in page editor? For example: I have a special menu, that i want to define with page editor, but it should be shown outside of page content.
So if i write in editor something like this, it should put this in my optional menu:
[menu]
<ul>
<li><a>Menu Item 1</a></li>
<li><a>Menu Item 1</a></li>
</ul>
[/menu]
<div>
Some content for my page
</div>
Is there some pugins or tricks or some filters etc. in wordpress for this?
