🐛 Feature 3: Multiple Buttons Fix

Problem

When multiple fields had button types (link_button, whatsapp_button), only the first button would work correctly due to:

• Non-unique class names
• No target="_blank" attribute
• Potential event conflicts

Solution

Added unique identifiers and proper attributes to each button:

Changes Made

File: assets/public.js

Before:

r = '<a href="'+r+'" class="button dw-checker-value-button">'+button_text+'</a>';

After:

r = '<a href="'+r+'" class="button dw-checker-value-button dw-checker-btn-'+id+'" target="_blank" rel="noopener">'+button_text+'</a>';

Improvements

1. ✅ Unique Class: dw-checker-btn-{field_id} for each button
2. ✅ Target Blank: Opens in new tab
3. ✅ Security: rel="noopener" prevents window.opener access
4. ✅ All Types: Fixed in all 4 display types

Applied To

• Link buttons (lines 125, 172, 238, 315)
• WhatsApp buttons (lines 127, 174, 240, 317)
• All 4 display types (vertical-table, div, standard-table, card)
