Selecting an extension from the list, or clicking the Expand View arrow
on the right side of the extension line, expands the default viewing level and displays a more detailed description of the selected extension, and any available directives. For information on configuring these directives, see Configuring Extensions and Directives.
Note:
Some extensions do not have directives. If you select such an extension , a "There are no directives for this extension" message is displayed under the extension's description.
The Expanded view includes:
- A full description of the extension
- Directives tab - A list of directives and related configuration controls:
Name | Control | Description |

Slide control | 
| Slide to turn directive on or off. |
Drop-down menu | 
| Click and select required value. |
- Messages tab - A list of extension-related messages (e.g., The directive 'bcmath.scale' value has been changed from '0' to '1'). Appears only if there are messages to be viewed.
