====== UI Patterns - Selection Controls ======

Author: Michelle

===== Examples =====

==== Checkboxes ====
Used when there are one or many options where more than 1 can be selected

==== Radio Buttons ====
  * Used when there are 2 or more options where 1 must be selected.
  * If possible, use radio buttons rather than drop-down menus - Making all options permanently visible so that users can easily compare them reduces cognitive load
  * It is better to have a selected radio button by default
  * Users cannot deselect and set the radio button back to its original state once one has been selected. If users might need to refrain from making a selection, you should provide a radio button labeled “None.” Structure the list of options in a logical order, and harness the power of suggestion

==== Toggle Switches ====
  * Used when there are 2 options and one must always be selected (with a default value)
  * Use toggles were selection will immediately take effect

==== Choice Chips ====
Compact alternative to radio buttons. At least 2 options where 1 can be selected.

==== Multi-Select Chips ====
Compact alternative to checkboxes. Primarily used for filtering on mobile

===== States =====
All of them have enabled, disabled, hover, focused, and pressed states.

===== Best Practices =====

==== Don't forget about the indeterminate state ====
  * The state is not fully determined
  * e.g. when there's a parent checkbox that has multiple children, some of which are selected and others are not.

==== Presenting options in the vertical list will help users easily scan them ====
Left-aligned controls and labels will work best - fastest completion times and fewer mistakes

==== Consider chips if vertical space is an issue ====
prevent a situation when it’s really difficult to see which control is selected ( make sure to space the buttons and labels)

==== Write clear labels, avoid negations ====
Avoid situations when users need to tick the box in order for something not to happen.

==== Highlight selected options to draw users attention ====
Visually differentiate selected options from others, especially important for rows selection in data tables.
