@DanGenEire I see these option basically.
You can make a case distinction and if your value says “All” you select a path that would not include any filters.
Another option could be to make some sort of reference where you will display something else and then put that into a filter:
All - “>0”
REG12 - “=1”
REG13 - “=2”
Maybe not the most elegant way but it should work
In this example the displayed colour in the widget is “blue” but the value submitted is “b”
Also the angle is displayed as strings (words) but the it is being ‘translated’ into a number within the Python node.
Maybe you can provide a sample to play with containing some dummy data.
