wxiaoguang d306ab2b8f Remove Fomantic-UI's .hidden CSS class for menu elements (#22895) ... * Like #22851 * All other dropdown menu elements do not have such `hidden` class. * Actually the dropdown menu elements do not need it in HTML, so this PR removes it. * There is already `.ui.dropdown .menu { display: none; }`, so when loading the page, the menu is correctly hidden initially, no need to add any more CSS classes. * The Fomantic UI's `.hidden` class should still exist until there is no its checkbox/dropdown module anymore. The Fomantic UI JS code still addes `hidden` for `ui checkbox` and addes `transition hidden` for `ui menu` at the moment. * This PR also cleans the legacy inline `style`, which is quite hacky and no need anymore. All these dropdown menus work well. I have tested these 5 places: * The code search from User Profile * The issue sidebar to lock issue * The repo search form * The repo setting page: branch list * The repo setting page: merge option list Screenshot: 		2023-02-14 19:53:54 +08:00
