I want to put an image on the top menu of my redmine plugin index page.
In init.rb
menu :top_menu, :my_link, {:controller => 'my_controller', :action => 'my_action'}, :caption => "My title" where could a link to any image fit in this syntax?
You'll have to do it with css.
If you create a menu with:
menu :top_menu, :my_link, {:controller => 'my_controller', :action => 'my_action'}, :caption => "My title"
It will be created with the class 'my-link'.
All you have to do is to define on your css:
#top-menu a.my-link {
padding-left: 20px;
background-image: url(../images/my-link.png);
}
