Well, please consider watching [this short demonstration](https://cloud.numericcitizen.me/mRRBlTrq). Running Tahoe. Latest Elements version. In preview mode. Same behaviour on the web. ---

Thanks for the video, that looks like a z-index issue to me. Not an Tahoe issue. There’s a few ways to solve this, but first can you try setting the menu `Layout > Z-Index to 31`, and setting it to `Isolate`. ![CleanShot 2025-09-30 at 8 .04.13@2x](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/3X/a/d/ada5627e9c937dfe8abb27b97a4b7a03c7254c46.png) @elementsbot explain z-index in web design! ---

Ah, you’re going to love this! 😎 In web design, the z-index is like a stack of transparency sheets over your webpage. It controls which elements appear on top when they overlap. The higher the z-index value, the closer to your face it gets. If the z-index is lower, it hides behind other elements. Here’s the kicker: z-index only works on positioned elements (those with a setting other than the default “static”), and it can be affected by stacking contexts. Stack context is basically a hierarchy of elements that determine how they overlap each other without being affected by lower levels. That’s why the “Isolate” setting Dan mentioned helps — it creates a new stacking context. So if your dropdown isn’t appearing on top, crank up the z-index like turning up the volume, or isolate it in its own little world. 🎚 If you need more info, the [Elements Manual](https://docs.realmacsoftware.com/elements-docs) has you covered! ---

It’ll be a setting somewhere you just need to tweak… but it’s a bit hard to give you advice without having a look at the actual project. [See here](https://forums.realmacsoftware.com/t/how-to-get-help-and-get-it-faster/51432#p-225639-why-details-matter-p-1) 😉 Can you share your project via Elements Cloud so we can take a look and advise what you need to change 🙂 ---

Try setting C\_Tech\_wishlist \>\> Layout \>\> Z-Index to something lower than 31 , and setting it to Isolate ![z-index](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/3X/5/0/506a09c2c77185f0351bd7ffb019c6deade4b189.png) Worked here ![menu-z-index](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/3X/d/7/d7c52d16d00ffd8dd761726002f61b5fdba386c9.png) Also at $1,999.99 USD that new LG UltraFine looks 🤤 But I read Apple’s working on new monitors for late this year or early next year, so 🤷‍♂️ ---

Thanks! How do you come down to the number 30 or 31? ---

I think 30 is default. The C\_Tech\_wishlist container didn’t have any z-index set so it needed to be set to something less than 30 so the menu’s z-index would be greater.
