How to make fields move up automatically when another field is hidden?

[yvesf]

Hi everyone,

In my nuBuilder form, I hide certain fields dynamically using JavaScript (for example, nuHide('fieldID')).
However, when a field is hidden, the other fields below it stay in the same position — leaving an empty gap.

Is there a way to make the following fields automatically “move up” to fill that space, similar to how elements flow in standard HTML layouts?

Ideally, I’d like to avoid manually repositioning each field if possible.
If it requires JavaScript or a specific layout technique (like subforms or div sections), I’d really appreciate some guidance or examples.

Thanks in advance!
