You may encounter a few different types of picklist fields in Salesforce.
- Standard picklists - Click the down arrow to select a single value.
- Multi-select picklists - Double click on any available value in one scrolling box to add that value to the selected scrolling box on the right. You can choose a single value or multiple values. To select values within a range, select the first value and click the last value in the range while holding down the SHIFT key; then, click the arrow to add selections to the chosen box.
- Dependent and controlling picklists work in conjunction with each other. The value chosen in the controlling picklist affects the values available in its dependent picklist. Both controlling and dependent picklists are indicated on edit pages by an icon. Hover your mouse over the icon to display the name of the controlling or dependent picklist.
