How to follow the link in the mobile version of the site only after the second click?

Question

linux

Hello! There is a menu with child directories. On PC, they are displayed on hover, while on mobile, you need to click. The problem is that when clicked, it jumps to the main directory, and it should only go after the 2nd click.
How can this be done?

Answer 1

Does the user running mysql have access to the files inside /var/lib/mysql?

Answer 2

Your InnoDB plugin is not initialized, so the process stops. Why - the reasons are different, the most banal - there is not enough memory. Sometimes there are problems with files

/var/lib/mysql/ib_logfile0
/var/lib/mysql/ib_logfile1

and removal helps.
I would start with the memory, reduce the settings a bit.
/var/lib/mysql/ibdata1 - DO NOT DELETE

Answer 3

Looks like mysql has problems with logs.
Try to transfer the logs
Then you can run. If there are no such files in /var/lib/mysql/, then check in /etc/mysql/my.cnf what values ​​the parameters have

innodb_data_home_dir

and

innodb_log_group_home_dir

And accordingly in this directory to look for log files. He swears like only on ib_logfile0

Answer 5

In general, for example, you can count the results of clicks and, depending on how many times you clicked, decide whether to go to the page or not. Example
But I think it's better to do it the other way. Next to the name of the item, make an arrow along which the submenu will open. Accordingly, if a person wants to go to a subdirectory, then he clicks on the arrow and the list drops out, otherwise he clicks on the word Catalog itself and he goes to it.
