How can I fix the issue with the multi-select dropdown not working when selecting multiple options in Webflow after integrating Memberstack?

If your multi-select dropdown isn't functioning properly after integrating Memberstack, it's likely due to script conflicts, incorrect field settings, or Memberstack interfering with native form behavior.

1. Check Form Element Settings

• Ensure the dropdown is set to "multi-select" in the custom code or plugin you're using (Webflow doesn’t support native multi-select dropdowns, so custom solutions or plugins like Select2 or Choices.js are typically required).
• Confirm that the dropdown uses a standard <select multiple> structure or equivalent setup from your chosen library.

2. Confirm Memberstack Content Protection Settings

• Go to Memberstack Dashboard → Content Protection and verify that the form or dropdown isn't inside a gated or conditionally hidden section.
• If the dropdown is hidden or dynamically loaded based on Memberstack’s user state, initialize the multi-select plugin after the content becomes visible.

3. Re-initialize the Multi-Select Script After Load

• Memberstack may alter the DOM or delay loading. This can interfere with your multi-select plugin.
• Ensure the plugin (like Select2 or Choices.js) is re-initialized after Memberstack finishes loading.

Example: If you’re using a custom embed, tie your script to the Memberstack.onReady function:

• Use window.MemberStack.onReady.then(function(member) { /* initialize select plugin here */ });

4. Inspect for JavaScript Errors

• Open browser developer tools (F12) and check the Console tab for errors.
• Conflicts between Memberstack and your multi-select script (e.g., jQuery, React, etc.) might cause failure to render or respond.

5. Avoid Duplicate jQuery Libraries

• If your multi-select plugin uses jQuery, ensure jQuery is loaded only once.
• Check in Page Settings → Before tag area to ensure you haven’t added jQuery manually if Webflow already includes it.

6. Test Without Memberstack

• Temporarily disable Memberstack script in your page’s custom code.
• Publish and test the multi-select. If it works without Memberstack, the issue is definitely a timing or interference problem.

7. Use a Delayed Initialization as a Temporary Fix

• Add a small setTimeout (e.g., 500ms–1000ms) before initializing your multi-select dropdown after page load. This gives Memberstack time to complete any async operations that might interfere.

Summary

The multi-select dropdown issue after integrating Memberstack is usually caused by DOM changes, delayed content loading, or script conflicts. Re-initialize your plugin inside MemberStack.onReady, avoid reloading libraries like jQuery, and inspect content gating settings inside Memberstack to restore full functionality.
