IPython - Run all cells below from a widget

Requirement is to from 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.

from IPython.display import display

w = widgets.SelectMultiple(

    description="Select up to five countries",

    options=dfCountries['name'].tolist()   

)

display(w)

Below is how to do it

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)
