"Hidden until triggered" buttons appearing on thumbnails in Publish Online
Hi!
I have created an ebook with navigational menu that opens up when clicked, using the reference from this tutorial which uses mainly Show/Hide buttons:
Then I used the Publish Online feature in InDesign. The navigation buttons work perfectly, but the only issue is that if I click on the thumbnails button, it shows the full navigation menu buttons which are supposed to be "Hidden until triggered". I have attached the image for easier reference (the highlighted greyed box is my navigation menu that should only open when I click on the top left burger menu button).
Does anyone have any idea why this is so, or is there a better way to creating the navigation menu?
Thanks in advanced!
