IPython - Run all cells below from a widget

Question

I\'m trying use a multi select widget to enable users to select from a list of countries, and then have a widget button which, when clicked, runs all the cells below.

If I understood correctly you could do that via js.

See the following code:

from IPython.display import Javascript
Javascript('IPython.notebook.execute_cells_below()')

Will execute all the cells below the active cell so for you button it could be something like:

from IPython.display import Javascript, display
from ipywidgets import widgets

def run_all(ev):
    display(Javascript('IPython.notebook.execute_cells_below()'))

button = widgets.Button(description="Create next input")
button.on_click(run_all)
display(button)

Let me know if this is what you need.
