Views, Grouping by various levels of granularity in a date field?

Question

I'd like to group a nodes in a view by date, but more specifically, I'd like Grouping field Nr.1 to be year and Grouping field Nr.2 to be the month.

Possible?

At current the test view looks like this:

I'd like it to look more like this

2015

November

• ibh Persto Torqueo Vel

October

• Commoveo Macto Premo Vel

September

• Ad Adipiscing Meus Nutus Tego Torqueo

2012

December

• Antehabeo Decet Pala Populus

April

• Quadrum Si Suscipit

Answer 1

Well I think I got it.

Step 1: Add two new date formats

I set up two new date formats: Month only and Year only

---

Step 2: Query the date date field twice under the new formats

Add the Publication Date field twice in these newly created formats

---

Step 3: Apply the proper grouping to the view

Here's how I grouped it....

And finally, the results

Below, albeit poorly formatted, I have two two years of 2015 and 2014 with sub divided months.

(For some reason, what ever the last grouped field is encapulated in . I tried playing with the formatting but no luck. However, I've worked out my logic here.)
