Hello, I’m new to Jmix. I have a problem. When I click the drawerToggle button in the main menu, the icons remain visible when minimized.

Hi,
The Vaadin’s AppLayout component that is used as a base for the StandardMainView doesn’t support icons only mode. You’ll need to implement a custom main view that meets your needs.

Hello, I came up with the answer myself. To implement what I wanted, you need to comment out drawerTogglе in the class responsible for your sidebar menu and add a custom button that performs the functionality you need. Then, write the logic for this button and add the class from the CSS file that describes how everything should be displayed on the screen to the main controller class that handles the display.
Something like this
