Set Up Dynamic Dropdown for Smartsheet

Follow these steps to configure SmartSyncApp's Dynamic Dropdown for Smartsheet. The entire setup process takes approximately five minutes. No coding, scripting, or formula knowledge is required.

Prerequisites

Before you begin, ensure you have:

• A Smartsheet account with access to both the source and destination sheets.
• Admin or Owner permissions on the source sheet (required for webhook registration by the Smartsheet API).
• At least one destination column that is set to Dropdown List or Text/Number column type in Smartsheet.

Step 1: Connect Your Smartsheet Account

Log in to SmartSyncApp and navigate to Dynamic Dropdown from the dashboard. If you have not yet connected your Smartsheet account, click Connect and authorize SmartSyncApp. The authorization uses Smartsheet's official OAuth flow and grants access only to sheets you explicitly select — no blanket workspace access.

Step 2: Prepare the Source Sheet

Your source Smartsheet sheet should contain a column with the master list of values you want to appear in destination dropdowns. Best practices for the source sheet:

• Add a unique identifier column such as Employee ID, Product SKU, or Vendor ID for data management.
• Include a Status column with standardized values like Active and Inactive for filter-based control.
• Include a Category or Region column if you want per-destination filtering.
• Remove duplicate rows or enable deduplication in the Dynamic Dropdown settings.

Step 3: Select the Source Column

In the Dynamic Dropdown configuration screen, select the source sheet and then select the specific column containing the values you want in destination dropdowns. For example, select Employee Name from an HR roster, Product SKU from a product catalog, or Vendor Name from an approved vendor list.

Step 4: Select Destination Columns

Choose one or more destination Smartsheet sheets and the specific columns where dropdown options should appear. You can add multiple destination sheets in a single mapping configuration — there is no limit on the number of destinations.

Step 5: Configure Filters (Optional but Recommended)

Apply filter rules to limit which source values appear in destination dropdowns. Common filter configurations for Smartsheet teams:

• Status = Active (exclude inactive, archived, or terminated items)
• Region = EMEA (territory-specific filtering for sales or support teams)
• Category = Electronics (category-specific subsets for procurement)
• Department = Engineering (department-specific employee lists)

Filters use exact matching including capitalization. Test filter values against the source data to confirm expected results before activating.

Step 6: Configure Sorting (Optional)

Choose how dropdown options are ordered for Smartsheet users:

• Alphabetical A-Z or Z-A for name-based lists (employees, clients, products).
• Numerical for priority-ranked items (projects sorted by urgency score).
• Custom order using a SortOrder column defined in the source sheet.

Step 7: Enable Deduplication (Recommended)

Turn on deduplication to automatically remove duplicate values from the dropdown list. This is especially important if the source column contains repeated entries or if multiple source rows share the same display value.

Step 8: Activate and Verify

Click Activate to start the sync. SmartSyncApp registers a webhook on the source Smartsheet sheet and performs an initial sync immediately.

To verify the setup is working correctly:

1. Add a test row to the source sheet with a distinctive, easily identifiable value.
2. Wait 10 to 30 seconds.
3. Open a destination sheet in Smartsheet and click on the mapped dropdown column to confirm the new value appears.
4. Remove the test row from the source and confirm it disappears from the destination dropdown.

Common Setup Pitfalls

• Missing permissions: The connected Smartsheet account must have access to both source and destination sheets. Re-authorize if permissions have changed since initial setup.
• Filter case sensitivity: Filter values must match source data exactly, including capitalization. "Active" and "active" are treated as different values.
• Wrong column type: Destination columns should be Dropdown List type in Smartsheet for the best user experience. Text/Number columns also accept the values but do not present them as a visual dropdown selector.
