Select

!!! tip "Added in version 0.24.0"

A Select widget is a compact control to allow the user to select between a number of possible options.

• Focusable
• Container

The options in a select control may be passed in to the constructor or set later with [set_options][textual.widgets.Select.set_options]. Options should be given as a sequence of tuples consisting of two values: the first is the string (or Rich Renderable) to display in the control and list of options, the second is the value of option.

The value of the currently selected option is stored in the value attribute of the widget, and the value attribute of the [Changed][textual.widgets.Select.Changed] message.

Typing

The Select control is a typing Generic which allows you to set the type of the option values. For instance, if the data type for your values is an integer, you would type the widget as follows:

options = [("First", 1), ("Second", 2)]
my_select: Select[int] =  Select(options)

!!! note

Typing is entirely optional.

If you aren't familiar with typing or don't want to worry about it right now, feel free to ignore it.
