There are a couple of ways you can link suppliers to specific product catalogs in Clappia:

Using Conditional Sections:
- Suppose you have a dropdown listing all suppliers. In Design App, group fields showing each supplier's catalog into separate sections.
- Click on each section, and in the right panel under Advanced, go to 'Display this field if' and enter @dropdown field name = \"Supplier Name\" (replace with the actual field name and supplier name). Repeat this for each supplier’s section.
- This setup ensures that only the catalog of the selected supplier will appear in App Home based on the dropdown choice.
Using the 'Get Data from Other Apps' Block:
- Create a separate app to store all supplier and product information, uploading the data as submissions.
- In your main app, use the 'Get data from other apps' block. In the right panel, under Data Source App, select the app containing supplier data.
- During configuration, specify which fields to pull based on the supplier selection. When the user selects a supplier in App Home, relevant products will auto-populate from the linked app.
- For more guidance on setting up this block, check Clappia’s documentation here.

Both methods effectively link suppliers to specific catalogs based on the dropdown selection. If these don't work for you, perhaps you can upload a screenshot of your app, to help you better. You can also try clicking on the 'Request tech support' button in the Design App, the solutions team will be able to provide you with the best outcome.
