Dropdown with custom input / Combo box

Describe the problem/error/question

Is there a way to have a dropdown field that also accepts custom input? I’ve tried using expressions but they only support the options already in the dropdown.

What is the error message (if any)?

Issues:

  • The value “custom value” is not supported!

Information on your n8n setup

  • n8n version: 1.118
  • Database (default: SQLite): default
  • n8n EXECUTIONS_PROCESS setting (default: own, main): default
  • Running n8n via (Docker, npm, n8n cloud, desktop app): npm
  • Operating system: WSL

Unfortunately, n8n’s dropdown fields don’t support custom input - they’re restricted to the predefined options only. You have a couple of workarounds:

• Switch the field to use an **expression** and manually type your custom value (like `custom value`) instead of selecting from the dropdown

• Use a **String** parameter type instead of dropdown if the node supports it

• Contact the FloTorch node developer to request adding your needed model to the dropdown options

The error you’re seeing is expected behavior since “custom value” isn’t in the predefined list of models that the FloTorch node recognizes.
