Description

When creating a select-like element with different values and labels, we can only access the value directly, but not the label.

Current way

import panel as pn
pn.extension()
radio = pn.widgets.RadioBoxGroup(
    name="MultiSelect Example",
    options={"one": 1, "two": 2, "three": 3, "four": 4, "five": 5, "six": 6},
    value=3,
)
radio

image

radio.value

image

Current workaround

def get_selected_label(radio_group):
    return list(radio_group.options.keys())[list(radio_group.options.values()).index(radio_group.value)]

selected_label = get_selected_label(radio)
print(selected_label)

image

Proposed solution

What I want is to access the selected label through a property.

Have a property such as

radio.label

image

That acts the same as the get_selected_label function above.

Contributor guide

Research direction
Look at the Panel widget source code, specifically the RadioBoxGroup class, to understand how options and value are stored, then add a 'label' property that returns the key from options corresponding to the current value.
