Question about Data-Driven Categories

[Ted]

Is there a way to create a data-driven category on just those images in a selected fixed category and it's dependents?

I have photos taken in multi country/cities. 
I have selected some of these photos to be displayed on a website (using Juicebox) by trip and date.  They are in a category of 'trip' and under it 'by date'.  This part I've done.

Now I would like to be able to create a data-driven category (of just the above photos) and break them down by country and city.

Seems like I should be able to do this with IMatch, but I'm stumped.  Any help would be appreciated.

Thanks.

Hi Ted,

You see here my settings.
For using only a category, see the helpfile for filtering. I have attached a part of it.
Hope this helps.

You can limit a data-driven category to one or more "input categories" by using the Category Filter near the top. See the help for details on how you can use this filter.

Thanks sinus and Mario.  The Category filtering does exactly what I was looking for.  I had looked in the help file but just hadn't found the right thing.
