I have a video of this in action, but my video editing skills to blur out the sensitive bits aren't so great, so I'm using screenshots for now. **1. The behavior you unexpectedly encountered** - When a Dock is set to "Cover" mode it switches to use "Push" Mode when viewing pages that have a URL Parameter. **2. The behavior you were expecting to see** - When set to cover mode the dock uses cover mode 100% of the time **3. A list of the steps you took that exposed the issue** - Created a page with a URL parameter for a Tank, so it could be passed a Tank number /StoreArea/Tank/Tank\_Num, and configured the page. When I started testing everything I noticed that if I open the dock while on the URL Parameter page (regardless of what parameter is passed in) the Dock switches to "Push" Mode. As soon as I navigate away from the URL Parameter page, it reverts back to "Cover" I have **not** had the time to try and recreate this from the ground up in a simple proof of concept project. **4. A list of helpful information about the situation you were in:** - Server OS: Windows 10 Pro Version 22H2 - Ignition Version: 8.1.25 was the inital version I saw the issue on, I upgraded to 8.1.31 and the problem remained. - Tested Client in Firefox 116.0.3, Chrome 116.0.5845.111, and MS Edge 116.0.1938.62 on Windows 11 - Tested Client in Chrome 116.0.5845.111 on Windows 10 (Ignition server machine) - Tested Client in Firefox 116.0.3, and Chromium 116.0.5845.96 on Arch Linux Attached are screenshots of the issue. ![MenuDock_Cover](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/2/f2a731edfebe62ec7dadf00459e38d9ff3a3f335.png) ![Normal_CoverMenu_2](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/2/b22c6f26ed6fc42685cbf1a5a7e0b7c129555928.png) ![Push_Menu_On_URLParam](https://us1.discourse-cdn.com/inductiveautomation/original/3X/4/9/49f461d58dd5012b612ee5d85bdc8f25ab021aa3.png) ![URLParamPage](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/1/b16f3ab3bf27fcef4d2a9ceec17fb036fb593e24.png) ---

Are you sure you set "cover" on all your page definitions? (Each page's dock definitions are separate.) ---

From your screenshots, it looks more like the issue is with corner priority, as the "cover" screenshot shows a top-oriented Docked View as having priority, while the "push" screenshot shows that same top Docked View as no longer having priority. While trying to replicate this with a simple scenario I was unable to, so we might need more information on your setup. Use the find/replace tool to search for the string "menu" in ALL Views (not just open views) to make sure you aren't using `system.perspective.alterDock` to modify the `menu` Docked View` within the project. There _is_ a top-oriented Docked View, correct? I'd like to verify that's not some unsupported CSS modification. Also, your screenshots appear to be from two different pages. Could you please share a screenshot of the "Tank" page where the Docked View demonstrates the expected "cover" functionality? ---

**SIGH** Yeah sorry guys, between a sick child and a new born my sleep hasn't been great. as @cmallonee pointed out it's even right there in my screenshot. For some reason on the URL Parameter Tank screen the corner priority was set left-right instead of inherited like everything else. I must have clicked it on accident while while creating the page config. Sorry for wasting your time, and thanks for the help.
