Placing Collections on Index


I am trying to create a little header with the 'collections' that I have created. I was reading the documentation for the functions however I did not found any function( or query ) that allowed me to show my Collection in my Index.


Do I follow you correctly that you want to add a collection to the front page of your site?

If so, and if you are using the newly-released Omeka 2.2, you can use shortcodes to add particular collections and HTML to a Simple Page, then make that simple page your front page in Appearance->Navigation

Well, what I want to do exactly is add all the collections I have created in the index (main site) like if it was a menu.

Ah! So, you mean having all of the collections there as navigation items, alongside where things like "Browse Items" and "Browse Collections" go by default?
