The Modify Drop-Downs window allows you to customize any of the drop-down lists that can be enabled via the interface style.
If you want to edit one particular list, click the Edit icon in the Type column in the record properties table.
If you want to edit all of the drop-down lists that are currently enabled in the interface style, click the Modify Drop-Downs button at the bottom of the interface style window.
For most of the drop-down lists, you can simply type inside the table and use the buttons to Delete Row, Insert Row or Move Up/Move Down. For the certain fields that can be enabled for process flow diagram (PFD) worksheets, an additional step is required as described next.
For the Operation Type and Operation Type Symbol fields that can be enabled for PFD worksheets, you will need to select an image to represent each option type.
To customize the list of available images, click the PFD Symbols button at the bottom of the Modify Drop-Downs window. This opens the Define PFD Symbols Images window, as shown next.
To add an image, click the Add button and select a file. The available formats are *.png, *.bmp, *.dib,*.gif, *.jpg, *.wmf and *.emf. The file name and image appear in the window.
To delete an image, click the image and then click Delete.
