Dropdown menu synchronized with multiples charts

Hi everyone.
I found in the documentation a way to add multiples dropdowns menus to a chart, but is it possible to have a single dropdown menu which synchronize mutliples graphics on the same chart ? (I also read a topic from last year and it said that was not possible).
Second question, is it possible for a single dropdown menu to synchronize multiples charts ?
Thanks all :slight_smile:

Not the native plotly.js dropdowns configurable via layout.updatemenus.

You’ll have to add your own as in https://plot.ly/javascript/dropdowns/#bind-dropdown-events-to-plotly.js-charts
