Attribute options
When adding a drop-down attribute definition, you can further specify its options.
1. On Attribute definitions level, create a new attribute definition of type Drop-down.
2. Select the newly created attribute definition and go to Attribute definition options level.
3. Add the options you require for this attribute definition and click Save.

•    If you select two attribute definitions at once and then go to Attribute definition options and proceed to add options, you must select the definition for which you are adding options.
•    You can add as many as 500 options to your attribute definition.
After specifying your options, you can proceed to attach your attribute definition to an asset or building element and your options can then be selected.
