Title: Force JavaScript in is breaking mobile menu Last modified: February 4, 2020 --- # Force JavaScript in is breaking mobile menu * [andremedinaw](https://wordpress.org/support/users/andremedinaw/) * (@andremedinaw) * [6 years, 4 months ago](https://wordpress.org/support/topic/force-javascript-in-is-breaking-mobile-menu/) * If I enable on: **JavaScript Options** - Force JavaScript in ? - and also - Add try-catch wrapping? - it makes the site really fast but when you tap on menu (mobile) it wont open I already tryed CSS, JavaScript all options and all works perfect but the only 2 options that makes a huge diference on speed but breaks the tap on mobile is that. Can you please help me to find a way to fix it and keep that 2 optins checked - Right now that options is not enable on my website, so mobile menu is working good at the moment. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fforce-javascript-in-is-breaking-mobile-menu%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 15 replies - 1 through 15 (of 15 total) * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years, 4 months ago](https://wordpress.org/support/topic/force-javascript-in-is-breaking-mobile-menu/#post-12396577) * Given “force JS in head” makes the JS render-blocking (meaning it will result in the first display of your page being slower) and that [“add try/catch wrapping” will result in the JS executing slower](https://blog.futtta.be/2014/08/18/when-should-you-trycatch-javascript/), I would advice against those settings actually andremedinaw 🙂 * Thread Starter [andremedinaw](https://wordpress.org/support/users/andremedinaw/) * (@andremedinaw) * [6 years, 4 months ago](https://wordpress.org/support/topic/force-javascript-in-is-breaking-mobile-menu/#post-12396614) * ok, thanks for the reply, but when enable it, the speed goes from 66 to 96 on page speed insights, that is why I´ll love to make it enable 😀 Is there any way to exclude the menu scripts * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years, 4 months ago](https://wordpress.org/support/topic/force-javascript-in-is-breaking-mobile-menu/#post-12396628) * Aha, the (un)holy grail 😉 * You could try adding `setup_collapsible_submenus` to the comma-separated JS optimization exclusion list maybe?
