How to create dependent dropdowns in Coda: step-by-step guide
Start by creating a new doc where we'll set up our dropdowns.
Create your first table to store the parent dropdown options (like Categories).
Add a column for your main dropdown values (e.g., "Electronics", "Clothing", "Food").
Create a second table for your child options (like specific products within categories).
In the second table, add a Lookup column that connects each item to its parent in the first table.
Use a Filter() formula in your form or where needed to show only options that match the selected parent value.
That's it! You've created dropdown menus that change based on previous selections. No rocket science required!
