Hi @Lobaloba1 and welcome to the Dash community 
It’s now possible to synchronize components with the latest release of Dash. Be sure to upgrade to v 1.19.0
See the examples in the announcement of this release:
https://community.plotly.com/t/dash-1-19-0-circular-callbacks-drag-value-in-dcc-slider-close-button-in-dev-tools-dcc-graph-bug-fixes/
Or see the last 3 examples in this chapter of the dash-docs:: Advanced Callbacks | Dash for Python Documentation | Plotly.
If you have more question, please describe what you are trying to do in a little more detail, and someone is likely to help.
