I think this is a good idea, but just want to confirm that these are replaced when you actually load a table and start an exploration.

[ahuang11]

Ok I added hide.

show.mp4

I always get confused using rx; specifically I couldn't get visible=self._explorations.param.objects.rx.bool() working. I also tried visible=param.rx(self._explorations.param.objects).rx.bool()

[philippjfr]

specifically I couldn't get visible=self._explorations.param.objects.rx.bool() working

Shouldn't it be self._explorations.param.objects.rx.bool().rx.not_(), i.e. make it visible when there are no explorations?

[ahuang11]

Yeah, but I get this error:

  File "/Users/ahuang/repos/lumen/lumen/ai/ui.py", line 500, in _table_explorer
    visible=self._coordinator.interface.param.objects.rx.bool().rx.not_()
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'function' object has no attribute 'rx'

[philippjfr]

Ah okay, it should be:

self._coordinator.interface.param['objects'].rx.bool().rx.not_()

The param accessor works like a dataframe column accessors, if the parameter name clashes with an existing method the method takes precedence.

[ahuang11]

Okay was able to use rx.
