Is it possible to group columns together, and then filter by group?

[moonpie100]

Hello All.

First off, I am new to power BI, so please bear with me (I am hoping I have included all necessary information).

I have searched to see if there were previous questions asked that are similar to my question but looking at other solutions, these solutions did not seem to fit exactly what I was looking for.

The sample data I am working with is classes, and number of students who attended those classes, and dates attended(screenshot below).

I was wondering if it was possible to group classes together, and then use the group as a slicer.

For example lets say class1 & class2 are math classes,  class3 and class4 are history classes, class5 and class6 are science classes.

I would then like to have a filter/slicer with options of math, history, science, so when when I select math, only class1 and class2 data are shown.

I am not sure if what I am wanting to do is possible.

Any help is appreciated.

Thank you in advance.

Hi,

Click on Edit Queries and right click on the first column > Unpivot Other columns.  Click on Add Column > Custom column and write this M formula there

=if [Attribute]="class1" or [Attribute]="class2" then "Maths Classes" else if [Attribute]="class3" or [Attribute]="class4" then "History Classes" else "Science classes"

Alternatively, after unpivoting, click on Close and Load.  Then go to Data Modelling and write this calculated column formula

=IF(OR([Attribute]="Class1",[Attribute]="Class2"),"Maths Classes",IF(OR([Attribute]="Class3",[Attribute]="Class4"),"History Classes","Science Classes"))

Hope this helps.
