It looks like your topic is missing some important information. Could you provide the following if applicable.

• n8n version:
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app):
• Operating system:

Would you like to map values from previous nodes? Or insert a static value?

If static, you can just type the value you want to insert there (without the curly brackets).
If dynamic (mapped from previous nodes), you could expand the editor to see all the available nodes and values to map on the left

Thanks. However, this is not the solution I need.

I am currently having a problem when updating values ​​in multi select property, the old values ​​will be deleted, I need to keep the previous old values ​​and update the new values. Is there any solution for this?

Ah, got it. Then, it needs to be an array that includes all the values you want to have. So, you would need to add both the existing values & the new values there, in an array format. Like the screenshot below
