Description

Description

Currently, Plotly gives you the option to customize the legend to either disable only the corresponding trace when you click on it, or the whole group at once with figure parameters groupclick="toggleitem" and groupclick="togglegroup".
There is no convenient way to set both types of switching at once.
For example, when you click on the name of a group in the legend to toggle all items in it, and if you click on a specific item to toggle only that item.
It would be great to have such a feature, as it is extremely useful for cases with big amount of traces in one group.

Research direction

Start by tracing the handling of the figure parameters groupclick="toggleitem" and groupclick="togglegroup", then inspect how legend clicks distinguish group names from individual items. Done means users can toggle an entire group from its name while toggling only the selected trace from an individual item, including for groups with many traces.
