When you want users to choose from a list of predefined alternatives, checkboxes and radio buttons are ideal.

•  If you want the user to select any number of options from a list, utilise checkboxes when creating a form. If you only want the user to make one choice, utilise radio.
• To make a sequence of checkboxes or radios for controls look on the same line, use the.checkbox-inline or.radio-inline classes.

Selects:

A select is used when you want the user to be able to choose from numerous possibilities, but it only allows one by default.

•  For list alternatives that the user is familiar with, such as states or numerals, use choose.
•  Allow users to choose from numerous options by using multiple = "multiple."
