Description
I noticed that there is a new algorithm, the Feature filter, in QGIS 3.2.0. I would like to see a similar algorithm in the modeller for filtering features for ranges for an attribute, such as attribute value = 0-20, 20-40, 40-60 and so on. That way, I could easily filter the features based on their properties without specifying every single value.

That's possible with the feature filter algorithm:
`"attr" > 0 AND "attr" <= 20`
Do you need something more than this?

I would like to filter the features into different groups, so I would need to use something like:
"attr" > 0 AND "attr" <= 20
"attr" > 20 AND "attr" <= 40
"attr" > 40 AND "attr" <= 60
I thought that "Feature Filter" would let me filter features into different groups for further processing, but I can´t get that to work. I only see one output.

See the following blog post for an exaplanation how to create multiple outputs:
If that is not working for this use case, please provide more details so we can see what's wrong (a model, screenshots, ...).

Yes, that helped. I guess I´m still not used to how Processing models work. I did of course have to catch the output in the following algorithm.
