[FEATURE] Mixed finite element support

[Cypher30]

Use case

I am working on various physics simulation problems and I am happy to see this project. However, my workflow frequently need the mixed finite element space. I saw the note in your documentation about the warning for no native support of Taylor-Hood like mixed element pair, I wonder if you can share a tentative timeline to work on this feature.

• I searched existing issues and discussions for similar requests.
• For larger features, I considered opening an Ideas & RFCs discussion first.

Hi Boyuan,

Thanks for your attention~
Mixed element is the first priority that we will upgrade in the next version. It will be finished in the following month ;-)

Btw, you can track the ROADMAP.md to check what we are going to add in the following several months.
