Breadcrumbs
The ePlan system displays the Breadcrumbs at the top of the main Header area. Breadcrumbs are a form of navigation were the current location within the website is indicated by a list of pages above this page in the hierarchy, up to the main page.
Breadcrumbs, basically inform you where you are in the system.
Drop Down Menus
Drop down Menus are a menubar, an item you can click that brings down a list of options to choose.
The Drop down menus in ePlan are indicated by an down arrow icon 
for example, when selecting a Time Limit you are required to click on the down arrow to open the Drop down menu.
Click on the required Time Limit to select and close the Drop down menu.
Check Boxes & Radio Buttons
Check Boxes are small boxes that you can check on or check off. Unlike radio buttons, Check boxes are mutually exclusive - the value of one Check Box is usually entirely independent of the value of any other.
Check Box:
Click me - I'm a Check box!
Radio Buttons are based on the metaphor of buttons on a car radio (for selecting a radio station), a Radio Button is a small button in a group of buttons where only one button can be selected at a time (unlike a Check Box).
Example of Radio Buttons:
Links
Links (hyperlinks) are a technique for organizing the objects in an application and establishing links between them. These links allow users to move to other modules or to other functionality within the application.
The ePlan application contains Links. These Links are identified by underlined text objects, for example Planning applications on the Navigation area of the Search Types screen.
