I am trying to find the way to create values for parameters that can be auto completed or show all available options with tab, like the value "allsigned" in the cmdlet
Set-ExecutionPolicy -ExecutionPolicy AllSigned
¿Any ideas about how this is called in programation or how can I achieve this ?

PowerShell has some neat, and often underused features that can be enabled to help you have that autocomplete functionality. You can enable it just for a certain PowerShell session or you can enable it so that every session has it enabled.
These parameters are added at runtime and are referred to as dynamic parameters because they're only added when needed. For example, you can design a cmdlet that adds several parameters only when a specific switch parameter is specified. Note. Providers and PowerShell functions can also define dynamic parameters.
The “$_” is said to be the pipeline variable in PowerShell. The “$_” variable is an alias to PowerShell's automatic variable named “$PSItem“. It has multiple use cases such as filtering an item or referring to any specific object.
How do I pass parameters to PowerShell scripts? Passing arguments in PowerShell is the same as in any other shell: you just type the command name, and then each argument, separated by spaces. If you need to specify the parameter name, you prefix it with a dash like -Name and then after a space (or a colon), the value.
