In Zap fields, dropdown menus are used to select and use possible values. Learn how to troubleshoot why your dropdown menu is empty or missing items.

In this example, we’re looking for a list in Trello called “Example List” that isn't appearing in the dropdown menu in the corresponding Zap field.

1. Check if your app account is connected

In the Zap editor, click to expand the step with missing dropdown menu items.
Click to expand the Account tab.
Click the dropdown menu and verify that you’re right app account is connected.

3. Check that the item exists

If the missing item still isn't showing up after you’ve reloaded the dropdown menu items, confirm in your connected app that the specific item actually exists, and make sure that it exists in the account that you’ve connected to Zapier.

Example

In the example of our Trello board, we’ll check that we’re using the right Trello account, and also that the list “Ideas” actually exists on the board called “Personal”.

4. Use a custom value

If there are too many items in your dropdown menu that they're not all loading at once—or causing an error—you can also use a custom value to input the ID of your item directly. Learn how to add custom values to dropdown menu fields in Zaps.

Note

Custom values are only a way to link to an item that already exists in your app. They are not a way to use an item that doesn’t exist in your app.

Tip

If you want to select a different item depending on a value from a previous step, you can use custom values to link to it instead.

If your dropdown menu is still empty or missing items after taking these troubleshooting steps, try reconnecting your app account.
