# Create a parameter list

When you create a graphic display that has tag placeholders, you can specify a parameter list that will supply tag or folder names, or parts of tag names, for the tag placeholders. At run time, you can use a parameter list to replace the tag placeholders with whatever string you have defined for the placeholder.

The parameter list option appears on various tabs of the Properties dialog boxes for the objects that use them, for example, the States tab of the Display Selector object, and the General tab of the Logout button object, and in the Initial graphics option in the Startup editor.

## To create a parameter list

1. Open the Properties dialog box of the object or the Startup editor and click the Parameter list button.
2. Click the browse button (...) to open the Tag Browser.
3. Select the first tag or folder to add to the list and click OK.
4. Repeat steps 2 and 3 for each additional tag in the list. Each tag in the parameter list text box is separated from the previous tag by a comma.

   Tip: | You can use a tag placeholder in curly brackets instead of a tag in a parameter list to pass a parameter forward from one display to another display that opens from it. The first tag in the list will replace #1 in the display expressions, the second tag in the list will replace #2, and so on. A parameter list stays with the object when it is copied or duplicated.
