shell-menu-select

A script that allows a user to use arrow keys to select an item from a list. Sometimes using select can be a bit clunky because the user doesn't get any visual feedback about what they're selecting unless a confirmation message is displayed (which adds more overhead).

New features

1. Table style menu
   • Added the possibility to display the menu in table style or list style with option -t (-t means table style)
   • Added the possibility to show first row as header of the table with option -sh (-sh means showHeader)
2. Added the possibility to insert options with | separator to create multi-column table (eg. options=("First option|First info" "Second option|Second info"))
3. Added selectedChoiceIndex to store index of the selected option
4. Added the possibility to type number to select an option
5. Added the possibility to quit typing 'q'
6. Improved handling of other keys different from arrow keys or numbers
7. Improved handling of colored options
8. Improved performance
