Hi
I am new to Bokeh. I am trying to add a radio button on data table.
Primarily, I am trying to add various widgets on my data table for making interactive selections.
Please let me know, whether this is possible in bokeh.
Regards,
Do you mean a radio button, literally in a DataTable row/column? AFAIK there are no built-in cell formatters or editors for this. One option would be to create custom extensions to Bokeh for "radio button" cell formatter and editor. This is not an entirely trivial task, but if you wanted to pursue this we would help and answer questions as best we could.
It is also *possible* that you might be able to use the existing HTMLTemplateFormatter in some way:
Basically by configuring it with an HTML template that has the button. But I have no direct experience to guarantee that this approach would work.
Thanks,
Bryan

Hi,
I made myself familiar with bokeh yesterday using the movies example app.
It’s a great template but I could not figure out how to add several tabs.
I want all tabs to look the same: widgets on the left, graph and table vertically aligned on the right.
How could I add a few tabs within this template?
Many Thanks & Regards,
