I would like to restart a discussion about the possibility of making a sticky hover tool in Bokeh. After researching and reading through previous discussions in the forums, it seems that the implementation of the InfoPane object would have addressed this need (https://github.com/bokeh/bokeh/pull/10231), but unfortunately, it was never completed.
Currently, it appears that there are complex workarounds to achieve this functionality [ Feature Request: HoverTool tooltips stick to a point on click. · Issue #5724 · bokeh/bokeh · GitHub, Feature Request: HoverTool tooltips stick to a point on click. · Issue #5724 · bokeh/bokeh · GitHub]. However, I am curious if there are any new ideas or updates on the development of a sticky hover tool in Bokeh.
When multiple data points overlap and we use the tap tool to open a new window, only the window of the top data point opens. The rest of the data points are inaccessible. With a sticky hover tool, the user can click on a stack of data points, and the tooltip will remain visible. This enables the user to select which data point’s window to open.
I would appreciate any insights or suggestions on implementing a sticky hover tool in Bokeh.
