# Enter variable selection options
|
|
|
|
**Selection Options** are a feature you can use to manage variable option selections. All selection options are optional, and they are off by default.
|
|
|
|
## Multi-value
|
|
|
|
If you turn this on, then the variable dropdown list allows users to select multiple options at the same time. For more information, refer to [Formatting multi-value variables]({{< relref "formatting-multi-value-variables.md" >}}).
|
|
|
|
## Include All option
|
|
|
|
Grafana adds an `All` option to the variable dropdown list. If a user selects this option, then all variable options are selected.
|
|
|
|
## Custom all value
|
|
|
|
This option is only visible if the **Include All option** is selected.
|
|
|
|
Enter regex, globs, or lucene syntax in the **Custom all value** field to define the value of the `All` option.
|
|
|
|
By default the `All` value includes all options in combined expression. This can become very long and can have performance problems. Sometimes it can be better to specify a custom all value, like a wildcard regex.
|
|
|
|
In order to have custom regex, globs, or lucene syntax in the **Custom all value** option, it is never escaped so you will have to think about what is a valid value for your data source. |
