Usnig OBS in Filter of a Custom Portlet

Hello,

I have added an OBS field in the Filter section of a custom portlet. This field filters project data for a particular level and levels under it.

I'd like the OBS field to filter on multiple levels.

For example, if the OBS has 3 levels, I'd like to be able to choose units from Level 1, 2 or 3.

1. If a unit from Level 1 is selected, it displays level 1, 2 and 3 data. This currently works as the OBS field = level1_unit_id.
2. If a unit from Level 2 is selected, it should display level 2 and 3 data.
3. If a unit from Level 2 is selected, it should display level 3 data.

How can points 2 and 3 be achieved using the same OBS filter field?

The above is very similar to how the OBS field in the Project List page works.

Thank you.

Regards
Jimmy
