dialog is a great tool for what you are trying to achieve. Here's the example of a simple 3-choices menu:

dialog --menu "Choose one:" 10 30 3 \
    1 Red \
    2 Green \
    3 Blue

The syntax is the following:

dialog --menu <text> <height> <width> <menu-height> [<tag><item>]

The selection will be sent to stderr. Here's a sample script using 3 colors.

#!/bin/bash
TMPFILE=$(mktemp)

dialog --menu "Choose one:" 10 30 3 \
    1 Red \
    2 Green \
    3 Blue 2>$TMPFILE

RESULT=$(cat $TMPFILE)

case $RESULT in
    1) echo "Red";;
    2) echo "Green";;
    3) echo "Blue";;
    *) echo "Unknown color";;
esac

rm $TMPFILE
