There are many filters you can base this on. Here are a few examples:

1. https://gitlab.kitware.com/paraview/paraview/blob/master/ParaViewCore/ServerManager/SMApplication/Resources/filters.xml#L2026-2041

Here the arrays to list is determined by the "InputArrayDomain"
element defined on the InputProperty and fixed to cell data.

2. https://gitlab.kitware.com/paraview/paraview/blob/master/ParaViewCore/ServerManager/SMApplication/Resources/filters.xml#L13865-13881

Here the user can separately select which attribute he/she is
interested in using a separate "AttributeMode" property.
