Title: Optimise JavaScript Code breaks menu dropdowns Last modified: May 20, 2020 --- # Optimise JavaScript Code breaks menu dropdowns * Resolved [davejeff66](https://wordpress.org/support/users/davejeff66/) * (@davejeff66) * [5 years, 11 months ago](https://wordpress.org/support/topic/optimise-javascript-code-breaks-menu-dropdowns/) * Hi, * If i check Optimise JavaScript Code it breaks the dropdowns in my navigation menu (“Home – About – Buddhism – What’s On – Groups”) – they no longer appear on hover. If I uncheck the option then they work again. Is there any way I can fix this? Optimising the JavaScript has the biggest impact on my pagespeed score so it’d be nice to use it. * Thanks! * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Foptimise-javascript-code-breaks-menu-dropdowns%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 5 replies - 1 through 5 (of 5 total) * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [5 years, 11 months ago](https://wordpress.org/support/topic/optimise-javascript-code-breaks-menu-dropdowns/#post-12865023) * its seems to work now and JS opt. is still on davejeff66 ? * ![](https://i0.wp.com/i.imgur.com/12ECxHc.png?ssl=1) * Thread Starter [davejeff66](https://wordpress.org/support/users/davejeff66/) * (@davejeff66) * [5 years, 11 months ago](https://wordpress.org/support/topic/optimise-javascript-code-breaks-menu-dropdowns/#post-12865066) * Hi, thanks for your super fast response. Sorry, yes, I’m just checking and unchecking boxes trying to work find out which configuration I can get away with and have the menu working correctly. For now it seems I cannot use “Also aggregate inline JS”, and I have to use both “Force JavaScript in ” and “Add try-catch wrapping”. It’s dropped my PageSpeed score some but that’s the only way I seem to be able to have “Optimise JS Code” active. Do you have any other suggestions or is this what I’ll have to stick with? * Thanks again for getting back to me so quickly, and thanks for a great plugin - This reply was modified 5 years, 11 months ago by [davejeff66](https://wordpress.org/support/users/davejeff66/).
