Creating dropdown option when setting up Python script into ArcToolbox? [closed]

Question

I created a script that I will import to an ArcToolbox. On the display name section, I have asked the user to choose a workspace, select the shapefile, field name, and an option to make a pdf, jpeg or none.

For the last option, instead of making the user write whether they want pdf, jpeg, or none, is there an option where I can create a dropdown menu with the 3 selection?

As commented by @hornbydd and @John:

Set the parameter to be of type TEXT then when you are in the properties dialog of the script tool you can create a LIST of values in the FILTER property of that parameter.

Multi-value, lists, filters, ranges, etc. http://desktop.arcgis.com/en/desktop/latest/analyze/creating-tools/setting-script-tool-parameters.htm
