**Hello I am proposing an idea for Tago to make a new widget called a Metadata Table Widget.
**
This widget would allow users to select a main variable and then select/define a nested metadata object to target. Then the table would dynamically create table columns based on the nested metadata object. See example JSON and how it would work:
{ “variable”: “fridge_data”, “metadata”: { “model”: “SmartCool X200”, “manufacturer”: “CoolTech Inc.”, “serial_number”: “CT-2025-XYZ-789”, “status”: “Running”, “stock_levels”: { “milk”: { “quantity”: 1, “unit”: “Liters”, “expiration_date”: “2025-02-20” }, “eggs”: { “quantity”: 12, “unit”: “Pieces”, “expiration_date”: “2025-02-18” }, “vegetables”: { “quantity”: 5, “unit”: “Kilograms” } } } }
Widget Configuration:
- Step 1: Select a main variable (e.g.,
"fridge_data"). - Step 2: Define which nested metadata object you would like to use (e.g.,
"stock_levels"). - Step 3: The widget dynamically extracts keys from that object and creates table columns.
- Step 4: Value of the keys are auto-populated into the table rows.
- Step 5: Automatically uses time and group from main variable.
How This Displays in the Widget
| Item | Quantity | Unit | Expiration Date |
|---|---|---|---|
| Milk | 1 | Liters | 02/20/2025 |
| Eggs | 12 | Pieces | 02/18/2025 |
| Vegetables | 5 | Kilograms | - |
Features of the Widget
- Auto detects nested metadata objects and generates columns dynamically
- Allows apps to become more scalable and flexible.
- Uses less data and I/O
- Keep all same features of dynamic table like filters, pagination, etc.
- Could even support links allowing users to navigate to other dashboards within the run app, open up widgets from hidden tabs, embedded images, trigger analysis, etc
I think this widget would be a game changer and could be very powerful and quick to build and offer in tago.io native widgets!
