Description

I use the slider as a date range selector. It has 2 possibles ranges, by month or by year.
I give the component an array with every periods and the ranger slider is like an index selector to get min and max value.
I have a first toggle button to help me chose which view to render.
When changing view, the value is updated but both thumbs are not rendered at the right positions.
