Hi

Thanks for contacting us. Could you please give me a screencast of your issue?

-Regards.

Video: https://drive.google.com/file/d/1IptNPi_nzmq_moxSlcJhCfDErWrF1uA7/view?usp=sharing Dropdown menu overlap other menus. I want set time delay about 3 sec

But sorry there is no default option to do this. You have to customize it yourself as we do not provide customization support.

Can you tell me where this setting is located? In what file?

You can follow this documentation below:
