JavaScript/jQuery Lookup - Lookup vs SelectBox
The Lookup and SelectBox UI components implement a similar functionality - while both consist of a text field and display a collection of items in the drop-down list, they also have differences:
- Drop-down field content 
 The SelectBox has only a list of items in a drop-down field whereas Lookup also has a search field and the Cancel button.
- Appearance on desktop and mobile devices 
 The SelectBox looks the same on any platform, while Lookup changes its appearance. The Lookup's drop-down field is replaced with a popup window that occupies most of the screen. This design optimizes Lookup for mobile devices.- SelectBox on any device - Lookup on desktop - Lookup on mobile devices
