Why is my debut drop down menu not responding?

Topic summary

Debut theme dropdown under the main “Shop” menu stopped responding. A developer identified the cause: Liquid (Shopify’s templating language) was mistakenly inserted into theme.js, breaking JavaScript.

Fix (confirmed by the original poster):

  • Online Store > Themes > Actions > Edit code
  • Assets > theme.js
  • Around line ~8880, remove the Liquid line shown in the referenced screenshot, then save.

Explanation: Mixing Liquid inside a JavaScript file caused the menu script to fail. After removing the line, the dropdowns worked again.

Subsequent updates: Multiple users report similar issues (unresponsive dropdowns/headers, invisible logo, footer menus not showing). Several provided store URLs. Some cannot find the same line or even a theme.js asset, suggesting different theme versions or different code edits, so the one-line deletion may not apply universally. Screenshots were shared by some users to illustrate missing dropdown icons and menu settings.

Status: Original issue resolved with the code removal. Later reports remain unresolved pending theme-specific debugging and identification of where Liquid or other breaking edits may exist.

Hi, I have drop down menus setup under the “shop” menu in my shops main menu. When I clicked on “Shop” all the drop downs used to show up, now suddenly I get no response when I click on “Shop”.

Thanks to anyone who can help

Please share:

  • your store URL;

Kind regards,

Do this to fix it in 20 seconds:

  1. In your Shopify Admin go to: online store > themes > actions > edit code
  2. Find Asset > theme.js
  3. Scroll down to the line 8880
  4. Delete this line that you see on the image and save.

Let me know if it works.

Yes!!! What happened?? Thank you so much!

Someone inserted liquid code instead of Javascript making your theme break.

You’re welcome!

By the way, since you’re using the Debut theme, I have a few tutorials that can improve your store. They are free and take like 30 seconds to implement:

  1. Enable swiping to product page images (improves UX and maximize potential of conversions);
  2. Add a sticky navigation bar, sticky announcement bar and control font size for navbar text.

@diego_ezfy , I am having a similar issue. Could you please help me?

I edited my code last night to remove text from my collection images, and afterward my dropdown and header menu became unresponsive. My header logo is also invisible now. I don’t want to revert my code due to it solving my collection text issue.
