 ### Dropdown and Set properties
 
-The option list for dropdown and set properties can be static or dynamic. Static options are defined with the `options` element of the property definition. Example:
+A `dropdown` allows you to select a single value from a series of options. A `set` allows you to select multiple values from a series of options.

-The list of options could be fetched dynamically from the server when the Inspector is displayed. If the `options` parameter is omitted in a dropdown or set property definition the option list is considered dynamic. The component class must define a method returning the option list. The method should have a name in the following format: `get*Property*Options`, where **Property** is the property name, for example: `getCountryOptions`. The method returns an array of options with the option values as keys and option labels as values. Example of a dynamic dropdown list definition:

-Dynamic dropdown and set lists can depend on other properties. For example, the state list could depend on the selected country. The dependencies are declared with the `depends` parameter in the property definition. The next example defines two dynamic dropdown properties and the state list depends on the country:
