The Kadence Blocks tabs block allows designers to organize content into tabbed sections, saving space and making information easier to digest. On desktop computers, clicking a tab header switches the visible content to the corresponding tab panel, and the whole interaction feels smooth and intuitive. However, when viewing the page on a mobile phone or tablet, the tabs may refuse to switch at all, leaving the first tab content visible and the other tabs completely inaccessible to users who tap on the tab headers.
This problem is particularly damaging for mobile users who may make up the majority of website traffic. When tabs do not work on mobile devices, visitors cannot access content that is hidden behind the non-functioning tabs, leading to frustration and a poor user experience. The tabs may appear correctly styled, but the JavaScript that handles the tab switching may not initialize properly on touch devices, or touch events may be blocked by other elements on the page.
The most common cause of this problem is that the tabs block is set to use “hover” instead of “click” for tab switching, and hover events do not exist on touch screens. Another cause is that a caching or optimization plugin is delaying the JavaScript file that controls the tabs, causing it to load after the user has already tapped on a tab header. JavaScript conflicts with other plugins that add touch event handlers can also prevent the tabs from responding correctly to taps.
Why Kadence Blocks tabs fail to switch on mobile devices
Kadence Blocks tabs rely on JavaScript to detect when a user interacts with a tab header and to show or hide the corresponding content panel. On desktop devices, both click and hover events can trigger the tab switch, but on mobile devices, only click events work reliably. Hover events do not exist on touch screens because there is no mouse cursor to hover with, so if the tabs are configured to switch on hover, they will not work at all on phones or tablets. Checking the tab block settings to ensure that the trigger is set to “click” rather than “hover” is essential for mobile compatibility.
Even when the trigger is set to “click,” mobile browsers handle click events differently than desktop browsers. A 300-millisecond delay exists on some mobile browsers between the tap and the click event firing, which can cause problems with certain JavaScript implementations. Additionally, if another element has a higher z-index and overlaps the tab headers on mobile, the tap never reaches the tab header at all because it is intercepted by the overlapping element. This is especially common with sticky headers or floating elements that cover parts of the page on mobile devices.
JavaScript optimization plugins that defer or delay JavaScript files can also cause tabs to fail on mobile devices. The script that controls the tabs may be delayed until after the user has already tapped on a tab header, and by the time the script loads, the tap event is no longer available. The tabs will appear to do nothing because the click handler was not attached to the tab headers when the user tapped them. This is particularly common on slower mobile connections where script loading times are longer.
How to check if Kadence Blocks tabs are configured for mobile
Edit the page containing the tabs block in the Gutenberg editor and click on the tabs block to open its settings panel. Look for the “Trigger” or “Toggle Method” setting, which determines whether tabs switch on click or hover. Ensure that this setting is set to “Click” rather than “Hover” for mobile compatibility. Also, check the responsive settings to ensure that the tabs are not being converted to a different component (like an accordion) on mobile devices, as this would change how they behave.
Step by step guide to fixing Kadence Blocks tabs on mobile
Follow these steps in order to restore proper tab switching functionality on mobile devices. Start with the simplest solutions before moving to more advanced troubleshooting steps.
- Check that the tabs block trigger is set to “Click” instead of “Hover” in the block settings
- Disable JavaScript defer or delay features for Kadence Blocks scripts in caching plugins
- Clear all caches including plugin cache, CDN cache, and browser cache completely
- Test the tabs on actual mobile devices instead of relying on browser simulation tools
- Check that no other element has a higher z-index and overlaps the tab headers on mobile
- Temporarily deactivate all other plugins to test for JavaScript conflicts
- Switch to a default WordPress theme to test if the theme causes the problem
- Update Kadence Blocks to the latest version available from the WordPress repository
- Use browser developer tools in mobile emulation mode to inspect for errors
- Contact Kadence Blocks support with specific details about the tab failure
How to exclude Kadence Blocks tabs from JavaScript optimization
In WP Rocket, navigate to Settings → WP Rocket → File Optimization and find the “Excluded JavaScript Files” field. Add the following handles to exclude Kadence Blocks tabs scripts from being deferred: kadence-blocks-tabs-js, kadence-blocks-js. In LiteSpeed Cache, go to Tuning settings and add the same handles to the JS Excludes list. After adding these exclusions, clear all caches and test the tabs on mobile devices again. This ensures that the tab switching script loads early enough to capture tap events on mobile devices.
Kadence Blocks tabs troubleshooting reference table
Here is a reference table for diagnosing tab switching problems in Kadence Blocks based on specific symptoms you might encounter.
| Symptom | Most likely cause | Recommended solution | Tabs work on desktop but not on mobile | Trigger set to Hover instead of Click | Change trigger to Click in tab block settings | Tabs do nothing when tapped on mobile | JavaScript delayed or not loading on mobile | Exclude Kadence scripts from defer/delay | Tabs switch but show wrong content | JavaScript conflict or corrupted tab data | Recreate the tabs block from scratch | Tabs work but are slow to respond | Mobile browser click delay or heavy page | Reduce page weight and optimize performance |

Preventing Kadence Blocks tabs problems on mobile in the future
Always set the tab trigger to “Click” instead of “Hover” when creating tabs blocks, as this ensures mobile compatibility from the start. Test tabs on actual mobile devices during the design process, not just in browser developer tools, because emulation can miss touch-specific issues. Exclude Kadence Blocks scripts from JavaScript defer and delay features in all caching plugins as soon as the website is launched to prevent mobile interaction problems.
Keep Kadence Blocks and all other plugins updated to their latest versions on a regular schedule, and clear all caches immediately after updating. Use a staging website to test major changes before applying them to the live production site, and regularly test the website on multiple mobile devices to catch issues before visitors report them. Document any custom exclusions added to caching plugins for future reference when troubleshooting similar problems.
