The RadioButtonGroup widget allows selecting from a list or dictionary of values using a set of toggle buttons. It falls into the broad category of single-value, option-selection widgets that provide a compatible API and include the RadioBoxGroup, Select, and DiscreteSlider widgets.

Discover more on using widgets to add interactivity to your applications in the how-to guides on interactivity. Alternatively, learn how to set up callbacks and (JS-)links between parameters or how to use them as part of declarative UIs with Param.

Parameters:

radio_group = pn.widgets.RadioButtonGroup(
    name='Radio Button Group', options=['Biology', 'Chemistry', 'Physics'], button_type='success')

radio_group

Like most other widgets, RadioButtonGroup has a value parameter that can be accessed or set:

radio_group.value

Styles

The color of the buttons can be set by selecting one of the available button_type values and the button_style can be 'solid' or 'outline':

pn.Row(
    *(pn.Column(*(
        pn.widgets.RadioButtonGroup(
            name=p, button_type=p, button_style=bs, options=['Foo', 'Bar', 'Baz'], value='Bar'
        )
        for p in pn.widgets.Button.param.button_type.objects
    ))
    for bs in pn.widgets.Button.param.button_style.objects)
)

Controls

The RadioButtonGroup widget exposes a number of options which can be changed from both Python and Javascript. Try out the effect of these parameters interactively:

pn.Row(radio_group.controls(jslink=True), radio_group)
