  1. Go to "Pickup Time Settings" in the app
  2. Enable "Pickup Time" to activate time slot selection
  3. Click "Add slot" to create time windows (e.g., 9:00 AM - 12:00 PM)
  4. Set maximum capacity for each slot
  5. Or click "Skip This Step" if you only need date selection

Step 3: Add Widget to Product Page

Add the delivery date picker to your product pages so customers can select their preferred delivery date before checkout.

  1. Go to your Shopify Theme Editor (Online Store > Themes > Customize)
  2. Navigate to a Product Page template
  3. Click "Add block" or "Add section"
  4. Select "Delivery Date Picker" from the "Apps" category
  5. Drag and drop it to your desired position (e.g., below the Add to Cart button)
  6. Click "Save"

Note: For cart page, checkout page, or thank you page display, go to Settings → Widget Display in the app.

Step 4: Test Your Setup

  1. Visit your store front
  2. Navigate to a product page
  3. Verify the date picker appears and blocks unavailable dates
  4. Add the product to cart and proceed to checkout
