I have seen other projects using form widgets such as 'radioSelectHorizontal' Is there a fully comprehensive list of widgets implemented in oTree, or will any wtforms widget work that way. (If I may leave a wish-list contribution for future versions, Streamlit Input Widgets would be very useful for a modern feel and look - https://docs.streamlit.io/library/api-reference/widgets )

The only form widgets you can explicitly select are RadioSelect and RadioSelectHorizontal (instead of drop-down list). Apart from that, widgets are automatically determined based on the field type (e.g. LongStringField uses a text area).

By the way I don't recommend using wtforms widgets. oTree uses wtforms internally, but using wtforms directly may malfunction, either in the current release or when you upgrade to a new release.

Thanks, Chris. I specifically need a numerical input with signs (or arrows) + and - that participants can click to change the default value in fixed steps (e.g. 0.05 units). I saw some slider implementations directly on HTML (with NoUIslider). Do you have any suggestions instead of Streamlit or wtforms widgets?
