Hi everybody,based on this article (https://metillium.com/2018/04/collapsible-section-page-layout-record-display-lightning-components/) I've tried to adapt and implement a custom page layout with collapsible sections with lightning web component.Currently everything works fine, BUT I didn't get it to work to open and close the section with transition so that is looks really smart.Currently the ui looks like the following:In comparison with the standard pagelayout there are very small differences for the layout.The arrow looks like a fat arrow:Could you give me a hint how to implement a transition to that the ui looks really smoothly and how to make my custom component look like teh standard layout section?Is there also the possibility to change the text color?Unfortunately I have only rudimentary knowledge about CSS.Best regards,
