Hey Alex,
The problem your facing is when you drag and drop the Parameter onto your CustomPanel its displaying all the constraint values at once. What you'll have to do is override the constraint values and delete the ones that you don't need to show up. You can do this by:
On your CustomPanel
1) Double Click on the parameter to open up the Edit Component window
2)Under The Parameter settings tab there should be an Override Constraint check-box
3) Click on the check-box to enable the ability to override constraint values
4) Delete the constraint values that are not necessary for your use case.
If you have anymore questions, please let us know and we'll get a response out to you as soon as we can.
Thank you,
Sadman
